Abstract

The heterometallic title complex, [Cr(2)Mn(2)(C(5)H(11)NO(2))(2)(C(5)H(12)NO(2))(2)(NCS)(4)]·4C(3)H(7)NO, was prepared using manganese powder, Reineckes salt, ammonium thio-cyanate and a non-aqueous solution of N-methyl-diethano-lamine in air. The centrosymmetric mol-ecular structure of the complex is based on a tetra-nuclear {Mn(2)Cr(2)(μ-O)(6)} core. The tetra-nuclear complex mol-ecule and the two uncoordinated dimethyl-formamide mol-ecules are linked by O-H⋯O hydrogen bonds, while the two other mol-ecules of dimethyl-formamide do not participate in hydrogen bonding.
