过渡金属配合物为模板合成两个新的硫代锡酸盐(英文)

Two New Thiostannates Templated by Transition Metal Complexes

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 thiostannates [Mn(en)(3)](2)Sn2S6.2H(2)O (en=ethylenediamine) (1) and [Mn(dien)(2)](2)Sn2S6 (dien=diethylenetriamine) (2) have been prepared under mild solvothermal conditions and structurally characterized by X-ray crystallography. Crystallographic data for 1: [Mn(en)(3)](2)Sn2S6.2H(2)O, M-r=936.28, monoclinic P2(1)/c, a=1.0129(3), b=1.574 6(4), c=1.152 4(3) nm, beta=102.36(1)degrees, V=1.795 5(8) nm(3), Z=2, D-c=1.732 g(.)cm(-3), mu(MoKalpha)=2.442 mm(-1), F(000)=940, R=0.063 3, wR=0.081 4; and for 2: [Mn(dien)(2)](2)Sn2S6, M-r=952.32, monoclinic P2(1)/c, a=1.248 12(3), b= 0.937 60(4), c=1.776 17(7) nm, beta= 121.752(2)degrees, V=1.767 5(1) nm(3), Z=2, D-c=1.789 g(.)cm(-3), mu(MoKalpha)=2.479 mm(-1), F(000)=956, R=0.057 9, wR=0.137 4. In, each complex [Sn2S6](4-) anions is composed of two SnS4 tetrahedra sharing a common edge. In the complex 1 the transition metal Mn cations are coordinated each by three en. ligands, while in complex, 2 the Mn cations are coordinated, each. by, two dien ligands. The metal complex templates make a significant influence on the arrangement of [Sn2S6](4-) anions in their crystal structures.
