| 摘要: 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=1.012 9(3)，b=1.574 6(4)，c=1.152 4(3) nm，β=102.36(1)°，V=1.795 5(8) nm3，Z=2，Dc=1.732 g·cm-3，μ(MoKα)=2.442 mm-1，F(000)=940，R=0.063 3，wR=0.081 4；化合物2的晶体学参数：C16H52Mn2N12S6Sn2，Mr=952.32，单斜晶系，P21/c，a=1.248 12(3)，b=0.937 60(4), c=1.776 17 (7) nm，β=121.752(2)°，V=1.767 5(1) nm3，Z=2，Dc=1.789 g·cm-3，μ(MoKα)=2.479 mm-1，F(000)=956，R=0.057 9，wR=0.137 4。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。 | |

| Abstract: Two new thiostannates [Mn(en)3]2Sn2S6·2H2O (en=ethylenediamine) (1) and [Mn(dien)2]2Sn2S6 (dien=diethylenetriamine) (2) have been prepared under mild solvothermal conditions and structurally characterized by X-ray crystallography. Crystallographic data for 1: [Mn(en)3]2Sn2S6·2H2O, Mr=936.28, monoclinic P21/c，a=1.012 9(3)，b=1.574 6(4)，c=1.152 4(3) nm，β=102.36(1)°，V=1.795 5(8) nm3，Z=2，Dc=1.732 g·cm-3，μ(MoKα)=2.442 mm-1，F(000)=940，R=0.063 3，wR=0.081 4; and for 2: [Mn(dien)2]2Sn2S6, Mr=952.32, monoclinic P21/c，a=1.248 12(3)，b=0.937 60(4), c=1.776 17 (7) nm，β=121.752(2)°，V=1.767 5(1) nm3，Z=2，Dc=1.789 g·cm-3，μ(MoKα)=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. CCDC: 246260, 246261. | |
