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.

Investigation systematic over magnetic susceptibility of the complex reveals the overall antiferromagnetic interaction between Cr(I) ion and Mn(III) ion through cyanide bridge and its 3D antiferromagnetic ordering behavior with typical metamagnetic character below 12.5 K.Figure optionsDownload as PowerPoint slide
