摘要
用过氧化物法合成、分离了Co23trieenClZnCl423tri=N2胺基乙基13丙二胺een=N乙基乙二胺体系中的部分异构体解析了其中两异构体的晶体结构。其中晶体属单斜晶系空间群P21/na=0.86114nmb=1.79069nmc=1.33747nmβ=107.6278°V=1.965316nm3Dc=1.713g·cm-3Z=4F000=1032μMoKα=27.43cm-1R=0.0725Rw=0.1798晶体同属单斜晶系空间群P21/ca=0.97993nmb=2.68159nmc=0.81073nmβ=107.5956°V=2.030511nm3Dc=1.658g·cm-3Z=4F000=1032μMoKα=26.62cm-1R=0.0660Rw=0.1536。两异构体中Co3+为六配位其差异仅表现在二元胺een中乙基的取向不同。晶胞中含4个配合物阳离子4个ZnCl42-阴离子。在结构单元中对映体的比例为1∶1。
Some geometric isomers of a new[Co (2, 3-tri)(een)Cl ][ZnCl 4 ](2,3-tri =N-(3-Aminoethyl)-1,3-propanediamine;een =N-et hylethylenediamine)system have been synthesised by decomposing per-oxide compl ex.The crystal stru ctures of two isomers?and?have been determined by single crystal X-ray diffraction analysis.The only difference between the two isomer s is the orientation of the substituted ethyl group in diami ne ligand(een).T he crystal?belongs to monoclinic space group P2 1 /n with a=0.8611(4)nm,b=1.7906(9)nm,c=1.3374( 7)nm,β=107.627(8)°,V=1.9653(16)nm 3 ,D c =1.713g·cm -3 ,Z =4,F(000)=1032,μ(Mo Kα)=27.43cm -1 ,R=0.0725,R w =0.1798;and the crystal?belongs to monoclinic space group P2 1 /c with a=0.9799(3)nm,b=2.6815(9)nm,c=0.8107( 3)nm,β=107.595(6)°,V=2.0305(11)nm 3 ,D c =1.658g·cm -3 ,Z =4,F(000)=1032,μ(Mo Kα)=26.62cm -1 ,R=0.0761,R w =0.1956.Both compounds are racemoids.
