The new compound [Mn(dien)2][Mn(dien)SbS4]2 (dien = diethylenetriamine) was synthesized under solvothermal conditions. It crystallizes in the non-centrosymmetric monoclinic space group P21 with a = 7.5736(5), b = 19.1081(16), c = 13.1174(11) Å, β = 90.022(9)○, V = 1898.3(3) Å3, and Z = 2. The crystal structure is composed of one [Mn(dien)2]2+ cation and an anionic chain composed of [SbS4]3− anions and [Mn(dien)2]2+ cations. The
[SbS4]3− anions connect [Mn(dien)2]2+ ions in a μ2-fashion to form an undulated {[Mn(dien)SbS4]}2− chain running along [001]. The Mn2+ ions in the chain are in a rare distorted rectangular pyramidal coordination environment with 3 N and 1 S atom forming the base and one S atom being located at the apex of the pyramid. The anionic chains and the cations alternate along [010]. Several relatively strong intra- and inter-chain N–H···S bonding interactions are observed. From the Raman spectrum the reduction of the ideal Td symmetry of the [SbS4]3− anions is obvious because more resonances occur than expected for the undistorted geometry.
