摘要

Hydrothermal reaction of 1,2,4-benzenetricarboxylic acid, and MnCl2·4H2O with 1,10-phenanthroline gave the title complex, [Mn(phen)(m-phth)]n, which crystallizes in the monoclinic system, space group P2/c with a＝0.83582(3) nm, b＝1.04246(4) nm, c＝1.87777(7) nm, β＝100.314(2)°, V＝1.60968(10) nm3, Z＝4, and the final R＝0.0576, wR＝0.1294. In the complex, each Mn(II) ion is coordinated to four O atoms of carboxylate groups and two N atoms of phen. Isophthalate was generated in situ through the loss of one carboxylate group of 1,2,4-benzenetricarboxylic acid under the hydrothermal condition. Each isophthalate is bound to three manganese atoms through O atoms of carboxylate in bridging and chelating fashion, affording manganese(II) pairs that are linked by the isophthalate group to yield a zig-zag chain along the c-axis.
