摘要
Two new three-dimensional coordination polymers, namely [Mn（L）（bpdc）]n（1）, [Mn（L）0.5（ndc）]n（2）（L = 1,4-bis（2-methylbenzimidazole）butane, H2 bpdc = 4,4＇-biphenyldicarboxylic acid, H2 ndc = 2,6-naphthalenedicarboxylic acid） have been successfully synthesized under hydrothermal conditions. Two complexes were characterized by physico-chemical, spectroscopic methods and single-crystal X-ray diffraction. Complex 1 shows a 3D → 3D 5-fold interpenetrated network with a 4-connected uninodal dia topology. Complex 2 possesses a 3D → 3D 3-fold interpenetrating architecture with a binodal（4,5）-connected xah topology. The fluorescence and thermal properties of the title complexes were discussed.
