摘　　要：Two coordination polymers have been synthesized from cpg/4,4＇-bipy/metal ions reaction system, [Zn（cpg）（4,4＇-bipy）0.5（H2O）]·H2O 1 and [Cd（cpg）（4,4＇-bipy）0.5（H2O）2]·H2O 2. X- ray analyses show that different coordination geometries of zinc and cadmium ions lead to similar ladder structures （tetra-for zinc ion and hexa- for cadmium ion）, in which all the flexible cpg molecules exist as single conformations of anti-form.Two coordination polymers have been synthesized from cpg/4,4＇-bipy/metal ions reaction system, [Zn（cpg）（4,4＇-bipy）0.5（H2O）]·H2O 1 and [Cd（cpg）（4,4＇-bipy）0.5（H2O）2]·H2O 2.
