Özet
The crystal structure of the title compound, [Ni2Cd(C17H16-
N2O2)2(C2H3O2)2(C3H7NO)2], contains discrete centrosymmetric hetero-trinuclear molecules in which Ni/Cd atom pairs
are triply bridged via O atoms from the SALPD2 [N,N0
-
bis(salicylidene)-1,3-propanediaminate] and acetate ligands.
The central CdII ion is in a distorted octahedral coordination
environment formed by four O atoms from two SALPD2
ligands in the equatorial plane and two O atoms of two
symmetry-related acetate ligands in the axial positions. The
symmetry-related NiII ions are in slightly distorted octahedral
environments, coordinated by two O and two N atoms from
tetradendate SALPD2 ligands in the equatorial plane, while
the axial positions are occupied by O atoms from a dimethylformamide and an acetate ligand. This results in the formation
of three edge-shared octahedra in which the NiCd distance
is 3.1482 (15) A˚ . The crystal structure is stabilized by weak
C—HO hydrogen bonds.
