Abstract
Abstract A series of deeply colored mixed valence complexes of the general formula [M(AA)2][M′X2(AA)2]Y4 were prepared and characterized, where M–M′=Pt(II)–Pt(IV), Pd(II)–Pt(IV), and Pd(II)–Pd(IV); (AA)=ethylenediamine, propylenediamine, and trimethylenediamine; X=Cl, Br, and I; Y=ClO4, BF4. The relationships between the reflection spectra and the nature of the constituents (X, (AA), Y and M–M′) of the compounds were studied. The value of \barνmax of the main absorption band in the visible region decreases in the order: Cl→Br→I, pn→tn→en, ClO4→BF4, Pd(II)–Pt(IV)→Pt(II)–Pt(IV)→Pd(II)–Pd(IV). On the basis of dichroism of the crystals, it can be predicted that the X–M′(IV)–X…M(II) atoms in these complexes are arrayed in a straight line parallel to the crystal needle.
