Synthesis and Crystal Structure of a Binuclear Manganese(II) Ternary Complex Derived From N-(2-pyridylmethylidene)taurine and 1,10-Phenanthroline

The title compound, 1, with the formula [Mn-2(pmt)(2)(1,10-phen)(2)]center dot 2ClO(4) [N-(2-pyridylmethylidene)taurine (abbreviated as pmt), consists of a structurally centrosymmetric dinuclear Mn-II complex and two discrete perchlorate anions. Each Mn center is six-coordinated with an N4O2 donors set of the pmt and 1,10-phenanthorline ligands, resulting in a compressed octahedral. In the crystal packing, the component cations interact with pairs of intermolecular C-H center dot center dot center dot O and pi-pi contacts forming a 2-D network. Also, the neighboring 2-D cationic layers are connected to each other with C-H center dot center dot center dot O interactions of perchlorate oxygen atoms with the separate C center dot center dot center dot O distances of 3.204(7)-3.365(8) angstrom, giving a supramolecular 3-D network.
