Six-coordinated {Mn(Ⅱ)} atoms are linked with carboxyl groups from camphoric acid ligands to form infinite one-dimensional chains. These chains are packed by means of hydrogen bonding and π-π stacking, forming a three-dimensional structure. IR, thermogravimetric analysis and magnetic susceptibility data for Mn(H_2O)(CA)(Phen)·H_2O are given.展开更多
