【Abstract】 Cyanide-bridged bimetallic coordination polymer [Cu(L)] 2[Fe 2(H 2O)(CN) 10 ]·8H 2O(L=1,8-Dipropyl-1,3,6,8,10,13-hexaazacyclotetradecane) was synthesized and structurally characterized. The coordination polymer crystallizes in the orthorhombic system of the space group Fddd with a=183.10(4)nm, b=260.60(5)nm, c=316.80(6)nm , α=β=γ=90°, V=15116(5) 3 , z=8, dc=1.085 g/cm 3, F(000)=5200, R 1=0.1024, W R 2 =0.2657, GOF(F 2)= 0.992. The one-dimensional chain extends through Fe-CN-Cu-NC-Fe linkages. The adjacent two polymer chains are linked by the Fe-O-Fe bond to form a two-dimensional extended structure.更多还原
