摘　　要：Two cyano-bridged heterobimetallic coordination polymers,[{Mn(dpa)2}2W(CN)8·CH3CN·4H2O]n(1)(dpa = 2,2'-dipyridylamine) and [Mn2(H2O)4{W(CN)8}·3H2O]n(2),have been synthesized and characterized structurally and magnetically.X-ray analysis shows that complex 1 is a one-dimensional(1-D) polymer of W2(CN)4Mn2 square units in which adjacent square fragments are interlinked by sharing [W(CN)8]4-moieties to form an infinite chain.Complex 2 is a three-dimensional(3-D) polymer,which shows an unforeseen structure,exhibiting a 3-D open network with a 1-D channel(ca.13.21 × 11.82 ).Fitting of the magnetic properties indicates that both polymers exhibit weakly antiferromagnetic interactions between the adjacent Mn ions.Two cyano-bridged heterobimetallic coordination polymers,[{Mn(dpa)2}2W(CN)8·CH3CN·4H2O]n(1)(dpa = 2,2'-dipyridylamine) and [Mn2(H2O)4{W(CN)8}·3H2O]n(2),have been synthesized and characterized structurally and magnetically.X-ray analysis shows that complex 1 is a one-dimensional(1-D) polymer of W2(CN)4Mn2 square units in which adjacent square fragments are interlinked by sharing [W(CN)8]4-moieties to form an infinite chain.Complex 2 is a three-dimensional(3-D) polymer,which shows an unforeseen structure,exhibiting a 3-D open network with a 1-D channel(ca.13.21 × 11.82 ).Fitting of the magnetic properties indicates that both polymers exhibit weakly antiferromagnetic interactions between the adjacent Mn ions.
