摘要
A novel zinc coordination polymer, [Zn2（bptc）（bpe）（H2O）]n （1, Habptc = 3,3＂,4,4＂- benzophenonetetracarboxylate, bpe = 1,2-bis（4-pyridyl） ethane）, has been prepared under hydrothermal conditions. The crystal structure is of monoclinic, space group C/2c with a = 27.50（2）, b = 6.207（4）, c = 16.233（11） A, β = 107.522（14）°, V= 2642 （3） As, C29H22N2O11Zn2, Mr = 705.27, Z = 4, Dc = 1.773 g/cm3, F（000） = 1432, p = 1.887 mm-1, R = 0.0421 and wR = 0.1049 for 2594 observed reflections （I 〉 20（/））. X-ray single-crystal diffraction analysis shows that 1 features two-dimensional [Zn2（bptc）（H2O）] layers, which are further linked by the bpe ligands to give rise to a three-dimensional pillar-layered structure. According to the topology analysis, this framework can be simplified into a （4,6）-connected （4^4.6＆2）（4^4.6^10.8） network.
