Hydrothermal Synthesis and Crystal Structure of a Novel Bipolymer[Ni_2(phen)_2(BTC)(H_2O)_6]·2H_2O

在水热条件下,成功合成出一例新型镍配位聚合物(CPs),[Ni2(phen)2(BTC)(H2O)6]·2H2O(化合物1,phen=1,10-菲罗啉,BTC=1,2,4,5-均苯四甲酸)。X-射线单晶衍射分析表明,化合物1属于三斜晶系,P1空间群,晶胞参数为ɑ=7.3604(5),b=10.9871(7),c=12.1984(8),α=66.787(6)°,β=76.531(6)°,γ=70.716(6)°,Z=2。结构分析显示化合物1是一个二聚物,并且通过配位水分子和均苯四甲酸配体上的配位原子形成的氢键进一步形成3D的超分子结构。

The new coordination polymers（CPs）, one novel nickel compounds, [Ni2（phen）2（BTC）（H2O）6]· 2H2O （compound 1, phen=1,10-Phenanthroline hydrate, BTC=1,2,4,5-benzene-tetracarboxylic acid）, were synthesized under hydrothermal conditions. Single-crystal X-ray diffraction analysis indicated that compound 1 was triclinic and crystallize in the P1 space group with a=7. 3604（5）A, b=10. 9871（7）A, c=12. 1984（8）A,α=66. 787（6）°,β=76. 531（6）°, γ=70. 716（6）°, and Z=2. Compound 1 was a dimer, which was further connected to a 3D supermolecular structure by hydrogen bonds between coordinated water moleculars and BTC ligands.
