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。
Under hydrothermal conditions, a new type of nickel coordination polymer (CPs), [Ni2 (phen) 2 (BTC) (H2O) 6] · 2H2O (compound 1, phen = BTC = 1,2,4,5-pyromellitic acid). X-ray single crystal diffraction analysis showed that compound 1 belongs to the triclinic system with P1 space group and the unit cell parameters are 60 = 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. Structural analysis shows that compound 1 is a dimer and further forms a 3D supramolecular structure by coordination of hydrogen bonds formed by coordination atoms on water molecules and pyromellitic acid ligands.
