| Abstract: Some geometric isomers of a new[Co(2,3-tri)(cmen)Cl][ZnCl4](2,3-Tri) =N-(3-Aminoethyl)-1,3-pr-opanediamine;cmen =1,2-Diaminopropane)system have been synthesised by decomposing per-oxide complex.The crystal stru ctures of two isomers(Ⅰ)and(Ⅱ)have been determined by single crystal X-ray diffraction analysis.The crystal?belongs to monoclinic with space gro up P21/c,a=1.0211(2)nm,b=0.9208(2)nm,c=1.9500(4)nm,β=97.907(4)°,V=1.8161(7)nm3,Dc=1.803g·cm-3,Z =4,F(000)=1000.00,μ(Mo Kα)=29.66cm-1,R=0.0317,Rw=0.0923,There are four complex cations which are enantiomers with a ratio of 1∶1 in a unit cell;and the crystal(Ⅱ)belongs to Triclinic with space grou P21,a=0.90953(18)nm,b=0.9694(2)nm,c=1.1771(2)nm,α=110.669(4)°,β=92.238(4)°,γ=91.211(4)°,V=0.9697(3)nm3,Dc =1.750g·cm-3,Z =2,F(000)=520.00,μ(Mo Kα)=27.84cm-1,R=0.0365,Rw=0.0975.There are two complex cations which a re enantiomers with a ratio of 1∶1 in a unit cell. |
