摘 要:报道了一维化合物{[Cu(trans[14]diene)SCN]2Mn(SCN)4(4,4′-bipy)·4H2O}n(trans[14]diene为5,7,7,12,14,14-六甲基-1,4,8,11-四氮杂十四环-4,11-二烯,4,4′-bipy为4,4′-联吡啶)的合成、表征和结构分析.该晶体属三斜晶系,具有P1空间群.a=0.95920(10)nm,b=1.06800(10)nm,c=1.7316(2)nm,α=84.400(10)°,β=74.850(10)°,γ=69.650(10)°,V=1.6053(3)nm3,Z=1,Dc=1.365g/cm3,F(000)=691,最终R[I>2σ(I)]=0.0474,R(全部)=0.0625,GOF(F2)=1.222.该化合物含[Mn(SCN)4(4,4′-bipy)n]2-链和两个[Cu(trans[14]diene)SCN]+阳离子.The studies of one dimensional compounds have attracted chemists for many interests, because they are not only important for molecular designing and magnetic materials, but also the basis of studying high dimensional compounds. Here we reported the preparation and X ray analysis of 4,4 bipyridine bridged one dimensional compound { Cu( trans 14 diene)SCN 2\5 Mn(SCN) 4(4,4 bipy)\54H 2O} n , where( trans 14 diene)=5,7,7,12,14,14 hexamethyl 1,4,8,11 tetraazacyclotetradeca 4,11 diene, 4,4 bipy=4,4 bipyridine. It crystallized in the triclinic system, space group P 1, with a = 0.959 20(10) nm, b = 1 068 00(10) nm, c = 1 731 6(2) nm, α =84 400(10)°, β =74 850(10)°, γ =69 650(10)°. V =1 605 3(3) nm 3, Z =1 , D c =1 365 g/cm 3, F (000)=691, final R I>2σ(I) =0 047 4, wR 1 =0 134 8, R (all data)=0 062 5, wR 2=0 146 8, GOF( F 2)=1.222. This complex is consist of a Mn(SCN) 4\5 (4,4 bipy) 2- chain and two Cu( trans 14 diene) SCN + ions.
