Di-?(2)-acetato-1:2?O:O';2:3?O:O'-bis-(N,N'-dimethyl-formamide)-1?O,3?O-bis-{?(2)-2,2'-[propane-1,3-diylbis(imino-methyl-ene)]diphenolato-1?O,N,N',O':2?O,O';2?O,O':3?O,N,N',O'-1,3-dinickel(II)-2-cadmium(II).

ABSTRACT: The crystal structure of the title compound, [Ni(2)Cd(C(17)H(16)N(2)O(2))(2)(C(2)H(3)O(2))(2)(C(3)H(7)NO)(2)], contains discrete centrosymmetric hetero-trinuclear mol-ecules in which Ni/Cd atom pairs are triply bridged via O atoms from the SALPD(2-) [N,N'-bis-(salicyl-idene)-1,3-propane-diaminate] and acetate ligands. The central Cd(II) ion is in a distorted octa-hedral coordination environment formed by four O atoms from two SALPD(2-) ligands in the equatorial plane and two O atoms of two symmetry-related acetate ligands in the axial positions. The symmetry-related Ni(II) ions are in slightly distorted octa-hedral environments, coordinated by two O and two N atoms from tetra-dendate SALPD(2-) ligands in the equatorial plane, while the axial positions are occupied by O atoms from a dimethyl-formamide and an acetate ligand. This results in the formation of three edge-shared octa-hedra in which the Ni?Cd distance is 3.1482?(15)?Å. The crystal structure is stabilized by weak C-H?O hydrogen bonds.

Bis{μ-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}dinickel(II).

Project description:The asymmetric unit of the title compound, [Ni(2)(C(16)H(14)N(2)O(2))(2)], contains an Ni(II) cation which is coordinated by two imine N atoms and by two phenolate O atoms of the salen ligand {salen = N,N'-bis-(salicyl-idene)ethane-1,2-diamine or 2,2'-[ethane-1,2-diyl-bis(nitrilo-methyl-idyne)]diphenol}, leading to a distorted square-planar conformation. When a secondary Ni-O inter-action > 2.41 Å to the neighbouring phenolate O atom is considered, two mol-ecules are linked into a centrosymmetric dimer with an overall square-pyramidal coordination for the Ni(II) cation. Weak π-π inter-actions with a shortest interplanar distance of 3.704 Å help to stabilize the crystal structure.
