Abstract
A bimetallic cyano-bridged complex {[Mn(ImH)(H2O)2]2[Mo(CN)8]·4H2O} n (ImH = imidazole) has been prepared and characterized. Single-crystal X-ray analysis reveals that the complex crystallizes in space group C2/c with a = 15.665(2), b = 14.616(2), c = 12.307(2) Å, α = 90, β = 108.31(1), γ = 90°. The structure of the complex demonstrates a three-dimensional network through cyano-bridges. Each Mo(IV) atom has six –CN–Mn linkages and two terminal cyano ligands arranged in a square antiprismatic arrangement. The Mn(II) atom is in a distorted octahedral environment formed by three MoCN → Mn linkages along with one imidazole and two water molecules in cis configuration. Variable temperature magnetic susceptibility shows an antiferromagnetic coupling between Mn2+ ions through the NC–MoIV–CN diamagnetic bridges within the three-dimensional network. The IR spectra have also been investigated.
