由Co(C lO4)2.6H2O和Sch iff碱吡啶-4-甲醛缩氨基脲反应合成了标题化合物[Co(H4FoPyS)2(H2O)4](C lO4)2.2H2O(1,H4FoPyS为Sch iff碱吡啶-4-甲醛缩氨基脲),其结构经IR,单晶X-射线衍射和元素分析表征。1属三斜晶系,空间群P,īa=6.9015(13),b=10.2030(19),c=11.136(2),α=104.960(3)°,β=90.090(3)°,γ=108.177(4),V=716.9(2)3,Dc=1.613 mg.m-3,Z=1,Mr=696.29,μ=0.868 mm-1和F(000)=359,最终偏差因子分别为R1=0.0857和wR2=0.2361。在1的晶体结构中,Co(Ⅱ)是六配位的稍变形八面体构型,其中2个吡啶氮原子和2个配位水分子占据赤道平面,另外2个配位水分子处于轴向位置。配合物分子通过氢键(N-H┈O和O-H┈O)相连,形成三维超分子网状结构。
The title compound [Co (H4FoPyS) 2 (H2O) 4] (C104) 2.2H2O (1, H4FoPyS is Sch iff base was synthesized from the reaction of Co (ClO4) 2.6H2O with Schiff base pyridine- Pyridine-4-carbaldehyde semicarbazone) whose structure was characterized by IR, single crystal X-ray diffraction and elemental analysis. 1 is a triclinic system with space group P, īa = 6.9015 (13), b = 10.2030 (19), c = 11.136 (2), α = 104.960 (3) °, 108.177 (4), V = 716.9 (2) 3, Dc = 1.613 mg.m-3, Z = 1, Mr = 696.29, μ = 0.868 mm- 1 and F (000) = 359 with final deviation factors of R1 = 0.0857 and wR2 = 0.2361. In the crystal structure of 1, Co (Ⅱ) is a hexagonal slightly distorted octahedral configuration, in which two pyridine nitrogen atoms and two coordination water molecules occupy the equatorial plane, while the other two coordination water molecules are in the axial direction position. Complex molecules through hydrogen bonds (N-H ┈ O and O-H ┈ O) connected to form a three-dimensional supramolecular network structure.
