Two octacyanomolybdate(IV)-M(II) (M = Mn, Co) bimetallic assemblies: Crystal structures and magnetic properties

Two cyano-bridged bimetallic complexes {[M2(H2O)4Mo(CN)8] · 4H2O}n [M = Mn (I) and Co (II)] have been synthesized and structurally characterized. The single-crystal X-ray analyses reveal that these two compounds have three-dimensional structures, and cell parameters are similar in a tetragonal system with space group I\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \bar 4 $$\end{document}. In the both complexes, each [Mo(CN)8]4− building block is linked with M2+ [M = Mn and Co] ions through its eight CN ligands. Each M2+ center is connected to four Mo units forming a three-dimensional framework. In addition, magnetic studies of these complexes have been presented.
