[CdCl2(C2H4(OH)2)]3 · C2H4(OH)2 — ein neuer Typ von Ethandiol-1,2-Koordinationsverbindungen

[CdCl₂(C₂H₄(OH)₂)]₃ · C₂H₄(OH)₂ — a New Type of Ethanediol-1,2 Coordination Compounds The coordination compound crystallizes with triclinic symmetry in space group P1 ; a = 10.418(2), b = 10.739(2), c = 11.053(2) Å, α = 86.04(2), β = 67.68(1), γ = 88.23(2)°; Z = 2, d_calc. = 2.32 g/cm³, R(F) = 0.031. The structure consists of Cd(C₂H₆O₂)Cl_4/2 octahedra with two edges (Cl double bridges) in common which form endless chains along [11 1]. A new orientational sequence of the unique ligand C₂H₆O₂ in the chain is found. The C₂H₆O₂ solvent molecule is located between the chains. Hydroxyl groups are involved in different H bridging systems which cause for all C₂H₆O₂ molecules a different conformation. This is confirmed by the results of IR and Raman spectra.
