利用溶剂热方法在温和的条件下合成了二个新的硫代锡酸盐[Mn(en)3]2Sn2S6·2H2O(en=H2NC2H4NH2)(1)和[Mn(dien)2]2Sn2S6(dien=H2NC2H4NHC2H4NH2)(2),通过X-射线衍射分析表征其晶体结构。化合物1的晶体学参数:C12H48Mn2N12S6Sn2·2H2O,Mr=936.28,单斜晶系,P21/c,a=1.0129(3),b=1.5746(4),c=1.1524(3)nm,β=102.36(1)°,V=1.7955(8)nm3,Z=2,Dc=1.732g·cm-3,μ(MoKα)=2.442mm-1,F(000)=940,R=0.0633,wR=0.0814;化合物2的晶体学参数:C16H52Mn2N12S6Sn2,Mr=952.32,单斜晶系,P21/c,a=1.24812(3),b=0.93760(4),c=1.77617(7)nm,β=121.752(2)°,V=1.7675(1)nm3,Z=2,Dc=1.789g·cm-3,μ(MoKα)=2.479mm-1,F(000)=956,R=0.0579,wR=0.1374。在两个化合物中存在的[Sn2S6]4-阴离子均由共边的两个SnS4四面体构成。在1中,锰离子螯合3个乙二胺做为阳离子模板,而在2中锰离子螯合2个二乙烯三胺做为阳离子模板。金属配合物作为模板对阴离子[Sn2S6]4-在晶体结构中的排列产生重要的影响。
Two new thionates [Mn (en) 3] 2Sn2S6 · 2H2O (en = H2NC2H4NH2) (1) and [Mn (dien) 2] 2Sn2S6 were synthesized by solvothermal method under mild conditions (dien = H2NC2H4NHC2H4NH2) (2), which is characterized by X-ray diffraction analysis. The crystallographic parameters of compound 1 are: C12H48Mn2N12S6Sn2.2H2O, Mr = 936.28, monoclinic, P21 / c, a = 1.0129 (3), b = 1.5746 (4), c = 1.1524 (3) nm, (MoKα) = 2.442mm-1, F (000) = 940, R = 0.0633, wR = 0.0814; V = 1.7955 (8) nm3; Z = 2; Dc = 1.732g · cm- The crystallographic parameters of compound 2 were C16H52Mn2N12S6Sn2, Mr = 952.32, monoclinic system, P21 / c, a = 1.24812 (3), b = 0.93760 (4), c = 1.77617 (7) nm, °, V = 1.7675 (1) nm3, Z = 2, Dc = 1.789 g · cm -3, μ (MoKα) = 2.479 mm -1, F (000) = 956, R = 0.0579, wR = 0.1374. The [Sn2S6] 4-anions present in both compounds consist of two co-edge SnS4 tetrahedra. In 1, manganese ion chelated 3 ethylenediamine as a cationic template, while 2 manganese ions chelated 2 diethylenetriamine as a cationic template. The metal complex as a template has an important effect on the arrangement of the anion [Sn2S6] 4- in the crystal structure.
