Abstract

AbstractA method is presented here that allows, in principle, the prediction of the existence and structure of (meta)stable solid compounds. It is based on a set of adjustable modules that are applied to the study of the energy function of the chemical system of interest. The main elements are a set of routines for global optimization and local minimization, as well as algorithms for the investigation of the phase space structure near local minima of the potential energy, and the analysis and characterization of the structure candidates. The current implementation focuses on ionic compounds, for which empirical potentials are used for the evaluation of the energy function in the first stage, and a Hartree–Fock algorithm for refinements. The global optimization is performed with a stochastic simulated annealing algorithm, and the local minimization employs stochastic quenches and gradient methods. The neighborhoods of the local minima are studied with the threshold algorithm. The results of this approach are illustrated with a number of examples: compounds of binary noble gases, and binary and ternary ionic compounds. These include several substances that have not been synthesized yet, but should stand a fair chance of being kinetically stable, for example further alkali metal nitrides besides Li3N, as well as Ca3SiBr2 or SrTi2O5.

  21. Strictly speaking most of the subsequent discussion deals with those structures that can be stabilized by energy barriers alone that is phases that could in principle exist atT= 0 K. For those phases that can only exist at high temperatures (e. g. the liquid state) we refer to the discussion in Section 6.3.
  22. The design and synthesis of a new compound correspond to the theoretical and experimental exploration of this energy landscape; thus a chemist plays a role closer to that of an intrepid discoverer of strange and foreign lands and less to that of a creator of new worlds.

  24. Note that the use of periodic boundary conditions does not imply anything about the final symmetry of the candidate structures.
  25. An alternative is the use of open boundary conditions that is the simulation of a cluster. To deal with surface effects this cluster should be embedded possibly in an effective medium which reflects the average interaction with the remainder of the solid .

  29. Depending on the objectives of the simulation one might want to exclude the ones with uninteresting properties. For example if one searches for insulators one would not want to spend time refining structures that exhibit metallic behavior.
  30. The term “state” refers to the electronic configuration of the atoms entering the approximate description of the solid such as ionic charge or “type” and occupation of orbitals.

  77. For several optimization runs the composition was allowed to vary freely too. In these cases the candidate structures were dominated by a close packing of the heavier atoms while the lighter noble gases tended to be removed from the simulation cell indicating that phase separation was a very important option for all of these systems.

  82. Note that our energy of formation with respect to the binary compounds is calculated atT= 0 K andp= 0 Pa while the experimental value is valid at standard conditions. Since the resulting difference in enthalpy is basically given by the integral over the specïfic heat and the contribution from the binary compounds will to a large degree cancel the contribution from the ternary compound the rough comparison we perform appears to be reasonable.

  92. It is curious to note that the energy differences of the local minima in Ca3SiBr2computed by using the effective potential were actually quite similar to those computed with the Hartree–Fock method (c.f. Section 5.2). This coincidence should not be over‐interpreted of course nevertheless their agreement shows that one might expect the optimizations using the simple effective potential to yield at least reasonable qualitative results.

  96. For example for the quaternary system Sr2NiO2Cl2 the best configuration we have found so far shows an A‐B‐A‐layer structure reminiscent of the K2NiF4structure in which each layer is based on a square O2−lattice with Ni2+filling every other square. Above and below each Ni2+ion a Cl−ion is placed resulting in an elongated octahedron around Ni. The Sr2+ions lie above and below those O2−squares that do not contain a Ni2+ion. Finally the Cl−ions “coat” the Sr‐Ni‐O layer leading to the NiO4Cl2octahedra and a O4Cl4coordination of Sr.
  97. One other observation of note is the fact that for the systems with many atoms in the simulation cell the sub‐optimal solutions tend to exhibit point defects (cf. Section 5.1). It is possible to “remove” the defects by performing considerably longer optimization runs. However the effective use of the computer resources becomes quickly an issue especially if the optimal candidate structures can already easily be perceived from the sub‐optimal structures containing these defects.
  98. Such an instance might be systems that show tendencies to form solid solutions of nearly equal size atoms.
  99. Note thatR(sometimes called an order parameter) is usually not a thermodynamic variable likeT p orV. Its definition is arbitrary and only represents one possible (but very useful if chosen cleverly) way to partition the configuration space.

  157. Since these penalty terms do not correspond to a physical energy term but only reflect some intuitive chemical or physical knowledge about the system they have to be treated very carefully when being assigned a quantitative meaning compared to terms from an effective potential.
