In our efforts to tune the structures of Mn(II) complexes by selection of organic carboxylic acid ligands, six new complexes [Mn(PIP){sub 2}Cl{sub 2}] (1), [Mn(PIP){sub 2}(4,4'-bpdc)(H{sub 2}O)].2H{sub 2}O (2), [Mn(PIP){sub 2}(1,4-bdc)] (3), [Mn(PIP)(1,3-bdc)] (4), [Mn(PIP){sub 2}(2,6-napdc)].H{sub 2}O (5), and [Mn(PIP)(1,4-napdc)].H{sub 2}O (6) were obtained, where PIP=2-phenylimidazo[4,5-f]1,10-phenanthroline, 4,4'-H{sub 2}bpdc=biphenyl-4,4'-dicarboxylic acid, 1,4-H{sub 2}bdc=benzene-1,4-dicarboxylic acid, 1,3-H{sub 2}bdc=benzene-1,3-dicarboxylic acid, 2,6-H{sub 2}napdc=2,6-naphthalenedicarboxylic acid, 1,4-H{sub 2}napdc=1,4-naphthalenedicarboxylic acid. All complexes have been structurally characterized by IR, elemental analyses, and single crystal X-ray diffraction. Structural analyses show that complexes 1 and 2 possess mononuclear structures, complexes 3, 4, and 5 feature chain structures, and complex 6 exhibits a 2D (4,4) network. The structural difference of 1-6 indicates that organic carboxylate anions play important roles in the formation of such coordination architectures. Furthermore, the thermal properties of complexes 1-6 and the magnetic property of 4 have been investigated. - Graphical Abstract: Through selecting organic carboxylate anions, six Mn(II) complexes have been synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction.
