  3. Crystal structure analysis:P63/mmc a= 2380.6(5) c= 2763.4(7) pm V= 13563(5) × 106pm3 Z= 2 ρcalcd= 2.67 g cm− 3; temperature: 193 K; structure solution with direct methods R= 0.063 for 3377 independent reflections (Fo> 4σ(Fo)). Details of the crystal structure and particularly of the complex cation lattice (particularly spectacular and grave errors in [5] which cannot be discussed in this work) of1are to be published in detail elsewhere. An important piece of information is for example that there is a significantly low occupation of the Na positions. No significant residual electron density could be located inside the cavity. The question of whether possibly “water” is present in the cavity cannot be answered conclusively either with the help of the X‐ray crystal structure analysis (possible disorder) or by taking into consideration the thermogravimetric data (mass contribution per H2O molecule is only ca. 0.2%). Further details of the crystal structure investigation may be obtained from the Fachinformationszentrum Karlsruhe D‐76344 Eggenstein‐Leopoldshafen (FRG) on quoting the depository number CSD‐57983.
  4. Additional characterization of1not mentioned in the text: correct elemental analysis for H251N18Fe6Mo57Na3O283(H N Fe); IR (KBr pellet some characteristic bands): v̄ = 1600 (m δ(H2O) and v(NO)) 945 (m) 910 (sh) 880 (vs all v(Mo = O)); characteristic bands in the Raman spectrum (λ = 1064nm): 960 (vs) 930 (m) 880 cm− 1(m all v(Mo = O)). The presence of (formally) six Movand six (MoNO)3+centers can be deduced from the redox titration with permanganate. An increasing delocalization of the 4d electrons which are obviously influenced in large species of the type1by the cation lattice seems to reduce the degree of protonation of the μ‐OH group in the [Mo(μ‐H2O)2‐(μ‐OH)Mo] moieties. The balance of charges might then take place by an increase of the number of cations—in the present case by further occupation of the Na positions [3].

  7. The compound “[H3O+]6[Mo57V6O183(NO)6(H2O)18]6−· 89H2O” given there is obviously false with respect to its composition structure and the oxidation states of the metal centers. Also the synthesis of this compound was not reproducable following the procedure provided by the authors; personal communication by P. Gouzerh University Pierre et Marie Curie Paris. The correct formulation for a compound obtained by us: (NH4)21[{VIVO(H2O)}6{Mov(μ‐H2O)2‐(μ‐OH)Mov}3{Mo(MoNO)O58‐(H2O)2}3]·65H2O (2)) [6]. The compound formulated as a neutral (!) complex by Zhang et al. (NH4)12[(MoVIO2)2{H12Mo(MoNO)O58(H2O)2}2] · 33 H2O (3). which contains the same Mo17ligand was described—unlike2—even with a false macrostructure. Compounds2and3were recently obtained by us in relatively high yields following a different route [6].

  22. An essential aspect is that clear quality and property changes or jumps (incidentally a fundamental problem in science) and furthermore also an increase in information in the sense of the definition given by C. F. von Weizsäcker emanate starting from a simple molecular region. This applies even more if the resulting systems do not represent a section of a typical solid‐state structure with approximated translational symmetry which also—according to von Weizsäckers approach—reduces the number of decision points. It is referred here to the concept of information as defined by von Weizsäcker since it will become important for the classification of molecular materials in the future (C. F. von Weizsäcker: (a.) “Information is the measure of amountof form…︁ matter has form …︁” (b) “The more decisions can be made about an object the more form in a general not necessarily spacial sense of the word can be recognized about it. This amount of form is as just stated a property of the object …︁”
