利用水热法合成了标题化合物[Zn(H4FoPyS)2(H2O)4](NO3)2.3(H2O)(1,H4FoPyS为希夫碱吡啶-4-甲醛缩氨基脲),其结构经IR,元素分析,单晶X-射线衍射和热重分析表征。1的晶体结构属三斜晶系,空间群P,īa=9.6505(16),b=12.644(2),c=13.156(2),α=115.459(3)°,β=90.0290(10),°γ=111.792(3),V=1321.1(4)3,Dc=1.609 g.cm-3,Z=2,M r=647.84,μ=1.905 mm-1和F(000)=728,最终偏差因子分别为R1=0.0365和wR2=0.0878。1中Zn(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。
The title compound [Zn (H4FoPyS) 2 (H2O) 4] (NO3) 2.3 (H2O) (1, H4FoPyS is a Schiff base pyridine-4-carboxaldehyde semicarbazone) was synthesized by hydrothermal method. Analysis, single crystal X-ray diffraction and thermogravimetric analysis. The crystal structure of 1 is triclinic with space group P, īa = 9.6505 (16), b = 12.644 (2), c = 13.156 (2), α = 115.459 ° γ = 111.792 (3), V = 1321.1 (4) 3, Dc = 1.609 g.cm -3, Z = 2, M r = 647.84, μ = 1.905 mm -1 and F (000) = 728, final deviation Zn (Ⅱ) is a hexacoordinated slightly distorted octahedron with R1 = 0.0365 and wR2 = 0.0878.1, respectively. Two pyridine nitrogen atoms and two coordination water molecules occupy the equatorial plane. The other two ligands Water molecules in the axial position.
