A H-bond induced two-dimensional in finite coordination polymer[Zn(1,3-BDC)(Im)2]n·2nCH3 OH(1,3-BDC =1,3-benzenedicarboxylate,Im =imidazole)was synthesized and crystallo-graphically determined by X-ray dif fraction.The crystal structure belongs to monoclinic system with space group C2/c.a=23.1836(2),b=10.1905(1),c=17.0118(2)?,β=115.099°,V=3639.58(6)?3,D=1.499g·cm-3,Z =8,F000=1688,μ=1.384mm-1,R1=0.0715,wR2=0.1645.Each Zn?ion is four-coordinated with a geome try of distorted tetrahedron.Each 1,3-BDC acts as a bridge to bond two neighboring zinc ions,leading to an infinite o ne-dimensional chainlike coordination polymer.Each chain wa s linked by hydrogen bonds with its neighbors to form a two-dimensional net.
