摘要
A new coordination compound of cis-bis(1,10-phenanthroline)glycinecobalt(Ⅲ) chloridate tetrahydrate,cis-[Co(phen)_2gly]Cl_2.4H_2O,has been prepared by glycine reacted with cis-[Co(phen)_2Cl_2]Cl,then isolated by SP-Sephadex C-25 H^+ form column. The crystal and molecular structure of the new compound has been determined by RIGAKU AFC5R four circle diffractometer,5032 independent reflections were collected of which 3781 observable reflections were used for structure refinement.The crystal is monoclinic,space group C2/c,with a=35.13(1),b=9.637(3)(,c=17.485(6),β= 115.08(Z)~,V=5362(3),Z=8.The structure was refined by full matrix least-squares procedure to a final R=0.041 and R_=0.060.The molecular formula was CoC_(28)H_(28)N_5O_8Cl_2. with molecular weight M_r=636.38,D_c=1.58g/cm^3,μ=8.88cm^(-1)and F_((000))=2624.
