Synthesis, crystal structure and magnetic properties of a new 2D cyanide-bridged heterobimetallic Cr(I)–Mn(III) complex

A new two-dimensional cyanide-bridged Cr(I)–Mn(III) coordination polymer {K[Mn(L)]2[Cr(CN)5NO]}·CH3CN (1) (L = N,N-ethylene-bis(3-methoxysalicylideneiminate)) has been successfully synthesized by the reaction of K3[Cr(CN)5NO] with [Mn(L)(H2O)2]ClO4 and characterized by elemental analysis, FT-IR and X-ray structure determination. Investigation systematic over magnetic susceptibility of the complex reveals the overall antiferromagnetic interaction between the cyanide-bridged Cr(I) ion and Mn(III) ion and its 3D antiferromagnetic ordering behavior with typical metamagnetic character below 12.5 K.
