利用水热法合成了标题配合物[Cu2(Hhbd)2(m phen)2].2H2O(H3hbd=羟基丁二酸,m phen=5-甲基-1,10-邻菲咯啉),对其进行了元素分析、红外光谱、热分析等表征,并测定了晶体结构。配合物属单斜晶系,空间群P 21/m;晶胞参数:a=1.1222(11)nm,b=1.2701(12)nm,c=1.2941(12)nm,β=103.498(7);°Z=4;最终偏离因子R=0.0483。配合物中两个羟基丁二酸根(Hhbd)采取三齿配位方式连接两个畸变的八面体Cu(II)配合单元,形成了新颖的双核结构。毗邻的双核结构通过O—H…O氢键和π-π堆积作用组装为具有隧道的三维超分子体系。
The title complex [Cu2 (Hhbd) 2 (m phen) 2] .2H2O (H3hbd = hydroxysuccinic acid, mphen = 5-methyl-1,10-phenanthroline) It was characterized by elemental analysis, infrared spectroscopy and thermal analysis, and the crystal structure was determined. The complex belongs to monoclinic system with space group P 21 / m. The unit cell parameters are a = 1.1222 (11) nm, b = 1.2701 (12) nm, c = 1.2941 (12) nm and β = 103.498 ° Z = 4; final deviation factor R = 0.0483. Two hydroxysuccinates (Hhbd) in the complex adopt three-tooth coordination to connect two distorted octahedral Cu (II) coordination units to form a novel dual-core structure. The adjacent dual-core structure is assembled into a three-dimensional tunnel-shaped supramolecular system by O-H ... O hydrogen bonding and π-π stacking.
