在盐酸水-甲醇介质中,三乙烯二胺(TEDA)、二乙胺(DEA)和由邻苯二胺(OPD)自缩合形成的 2,3-二氨基吩嗪(DAP)发生质子化形成有机铵阳离子,四氯化锡转化为六氯合锡阴离子.通过氢键和离子对作用,有机铵阳离子与六氯合锡阴离子自组装成有机-无机超分子杂合物,[(H2 TEDA)(SnCl6 )](1 ),[(HDEA)2 (SnCl6 )](2),[(H2 DAP)(SnCl6 )](3).杂合物的晶体分子结构经 X-射线衍射方法测定确证.化合物(1 )和(3)的晶体属于三斜晶系,分别为P-1 和P1 空间群,化合物(2)的晶体属于单斜晶系,P2(1)/n 空间群.晶体中,六氯合锡阴离子具有变形八面体构型,有机组分与无机组分穿插排列,形成(1 )和(3 )三维、(2 )为二维的超分子结构,为进一步新材料研究奠定基础.

In aqueous hydrochloric acid-methanol medium,the 2,3-diaminophenaz(DAP)is formed by means of the self condensation reaction of o-phenylenediamine(OPD),and the triethylenediamine(TEDA),the diethylamine(DEA)and the diaminophenaz(DAP)is protonated to produce organic ammonium cationa,(H2 TEDA)2+,(DEA)+,(H2 DAP)2+,and also,the tin tetrachloride is converted into hexachlorostannate anion respectively.A series of organic-inorganic hybrid compounds with supramolecular structure,YSnCl6[Y:H2 TEDA(1),(HDEA)2(2),H2 DAP(3)]is self-assembled by hydrogen bonds and ion pairs interaction between organic ammonium cationa and hexachlorostannate anion.The composite was characterized by X-ray crystal diffraction analysis method.The compounds(1),(3)crystallizes in the triclinic system,space groups P-1 and P1,respectively.The compounds(2),crystallizes in the monoclinic system,space group P2(1)/n.In crystals,the hexachlorostannate anions exhibit distorted octahedral configuration.Organic and inorganic components interlace to form(1),(3)is a two-dimensional,and(2)is a three-dimensional supramolecular structure and to lay a foundation for the further investigations of the material.
