VOLATILE ZNPHEN(S2CNET(2))(2) AND MNPHEN(S(2)CNET(2))(6) COMPLEXES AND THE MNZN(2)PHEN(3)(S(2)CNET(2))(6) PHASE - THERMAL-BEHAVIOR AND CRYSTAL AND MOLECULAR-STRUCTURES OF 2 MODIFICATIONS OF ZNPHEN(S(2)CNET(2))(2)

Two crystal modifications, I and II, of the ZnPhen(S(2)CNEt(2))(2) com plex have been isolated According to XRD data, the single crystals of I are triclinic with a = 9.745(2), b = 10.252(2), c 14.331(3) Angstrom , alpha = 99.18(2), beta = 91.01(2), gamma = 113.28(2)degrees, V = 129 3.2(4) Angstrom(3), space group P (1) over bar, Z = 2 d(calc) = 1.401 g/cm(3). The crystals of II are monoclinic with a = 7.220(6), b = 18.0 95(2), c = 19.050(4) Angstrom, beta = 95.85(2)degrees, V = 2475.8(7) A ngstrom(3), space group C2/c, Z = 4 d(calc) = 1.461 g/cm(3). In both m odifications, the structure is formed by monomer molecules with a dist orted octahedral environment of the zinc atom. All atoms in I are in t he general position; in II, the atoms are linked by the twofold rotati on axis. It is shown by X-ray phase analysis (XRPA) that the MnPhen(S( 2)CNEt(2))(2) complexes (III) are isostructural to modification I of t he ZnPhen(S(2)CNEt(2))(2) complex which underlies the synthesis of a s olid solution of these complexes, MnZn(2)Phen(3)(S(2)CNEt(2))(6) (phas e IV). It is found that MPhen(S(2)CNEt(2))(2) (M = Zn2+, Mn2+) and pha se IV quantitatively, sublime when heated in vacuum. Thermolysis of II I in argon yields manganese(II) sulfide of cubic modification; the mai n product of thermolysis of phase IV is a solid solution of ZnxMn1-xS of hexagonal modification.
