We report the crystal structure and magnetic properties of a two-dimensional cyano-bridged MnII(S = 5/2)-NbIV(S = 1/2) bimetal assembly (1), and the magnetic properties of an isostructural cyano-bridged MnII-MoIV(S = 0) bimetal assembly (2). 1 contains 3-hydroxypyridine ligands with four types of coordination arrangements, includes μ-oxo-bridged Mn-Mn sites, and shows ferrimagnetism with a Curie temperature of 16 K due to the antiferromagnetic MnII-NbIV superexchange interaction through the cyano groups. 2 exhibits paramagnetism with the antiferromagnetic interaction between Mn and Mn through the μ-oxo-bridges.
