[CdCl2(C2H4(OH)2)]3 · C2H4(OH)2 - a New Type of Ethanediol-1,2 Coordination CompoundsThe 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, dcalc. = 2.32 g/cm3, R(F) = 0.031. The structure consists of Cd(C2H6O2)Cl4/2 octahedra with two edges (Cl double bridges) in common which form endless chains along [111]. 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.
Notes:
Die Koordinationsverbindung kristallisiert triklin in der Raumgruppe 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, dber. = 2,32 g/cm3, R(F) = 0,031. Die Struktur besteht aus den Koordinationsoktaedern Cd(C2H6O2)Cl4/2, die über zwei gemeinsame Kanten (Cl-Doppelbrücken) unendliche Ketten längs [111] bilden. Dabei tritt eine neue Variante der gegenseitigen Anordnung der ausgezeichneten Ethandiolliganden auf. Das Solvat-C2H6O2-Molekül befindet sich zwischen den Ketten. Durch unterschiedlichen Einbau der OH-Gruppen in H-Brückenbindungssysteme werden alle C2H6O2 konformativ unterschiedlich, wie auch IR- und Raman-Spektren zeigen.
