THE SYNTHESIS AND CRYSTAL STRUCTURE OF CIS-BIS(1,10-PHENANTHROLINE)GLYCINECOBALT(Ⅲ)

摘要

A new coordination compound of cis-bis（1,10-phenanthroline）glycinecobalt（Ⅲ）chloridate tetrahydrate,cis-[Co（phen）2gly]Cl2.4H2O,has been prepared by glycinereacted with cis-[Co（phen）2Cl2]Cl,then isolated by SP-Sephadex C-25 H+ form column.The crystal and molecular structure of the new compound has been determined by RIGAKUAFC5R four circle diffractometer,5032 independent reflections were collected ofwhich 3781 observable reflections were used for structure refinement.The crystal ismonoclinic,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-squaresprocedure to a final R=0.041 and R=0.060.The molecular formula was CoC28H28N5O8Cl2.with molecular weight Mr=636.38,Dc=1.58g/cm3,μ=8.88cm-1and F（000）=2624.
