Abstract
In the crystal of the title compound, [MnNi(CN)4(C3H7NO)2] n , both metal cations lie on sites of 2/m symmetry, with the NiII ion being four-coordinate square-planar and the MnII ion being six-coordinate octa-hedral. Both coordination spheres are slightly distorted from the ideal shapes. The {C≡N→Mn} unit is distinctly non-linear and all four cyanido ligands on each [Ni(CN)4]2- unit coordinate to MnII ions, leading to the formation of an infinite layer structure. Bond lengths and inter-bond angles are comparable to those in similar dimetallic, cyanido-bridged compounds.
