在水和甲醇的混合溶剂中,经邻菲绕啉、丁二酸钠和CuOl2·2H2O反应合成得到标题配合物,[Cu2(phen)2(OH)Cl(C4H4O4)]·8H2O.单晶 X-射线衍射分析表明,晶体属单斜晶系, P21( No. 4)空间群,晶胞参数:α=0.7708(1)nm,b=1.7861(3)nm, c=1.2489(2)nm,β=9689(1)°,V= 1.7070(5) nm3,Dc=1.557 g/cm2,Z=2,F(000)=824,4282个独立衍射点中,3348个可观测点满足F20≥2σ(F20),R=0.062,ωR2=0.1634.[Cu2(phen)2(OH)Cl(C4H4O4)]·8H2O配合物由双核铜[Cu2(phen)2(OH)Cl(C4H4O4)]络分子和晶格H2O分子组成.每个Cu原子与邻菲绕啉上的2个N原子、丁二酸根上的1个羧基O原子、1个桥联Cl原子及桥联氢氧根上的O原子配位形成高度畸变的三角双锥.通过Cl原子、氢氧根及丁二酸根一端羧基的桥联作用,相邻三角双锥形成“蝎子”形的双核[Cu2(phen)2(OH)Cl(C4H4O4)]络分子.分子间的芳环堆积作用致使双核络分子排列形成平行于晶?
The title complex, [Cu2 (phen) 2 (OH) Cl (C4H4O4)] · 8H2O was synthesized by the reaction of phenanthroline, sodium succinate and CuO12 · 2H2O in a mixed solvent of water and methanol. Single crystal X-ray diffraction analysis showed that the crystal belongs to the monoclinic space group P21 (No. 4) with unit cell parameters of α = 0.7708 (1) nm and b = 1.7861 (3) nm. = 1.2489 (2) nm, β = 9689 (1) °, V = 1.7070 (5) nm3, Dc = 1.557 g / cm2, Z = 2, F (000) = 824,4282 independent Of the diffraction spots, 3348 observable points satisfy F20≥2σ (F20), R = 0.062, and ωR2 = 0.1634. The [Cu2 (phen) 2 (OH) Cl (C4H4O4)] · 8H2O complex is composed of Cu2 (phen) 2 (OH) Cl (C4H4O4) molecules and lattice H2O molecules. Each Cu atom coordinates with two N atoms on phenanthroline, one carboxyl O atom on succinate, one bridged Cl atom and O atom on bridged hydroxyl to form highly distorted triangular bis Cone. Through the bridging effect of Cl atom, hydroxyl group and carboxyl group on the one side of succinate, the adjacent triangular double cones form a “scorpion” binuclear [Cu2 (phen) 2 (OH) Cl (C4H4O4)] molecule. Aromatic ring accumulation between the molecules led to the formation of dual nuclear molecules parallel to the crystal?
