| Abstract: A Zn(Ⅱ) coordination polymer [Zn(pht)(pzH)2]n (where pht2-=dianion of o-phthalic acid, pzH=pyrazole) has been synthesized and the structure was determined by X-ray diffraction. The complex crystallizes in the monoclinic space group P21/c, a=0.821 39(10) nm, b=1.662 2(2) nm, c=1.156 42(14) nm, β=100.349(2)°, V=1.5532(3) nm3, Z=4. Both carboxylate groups of the phthalate dianion coordinated in a monodentate mode bridged two Zn(Ⅱ) atoms forming the structure of 1-D chain. The pyrazole ligands play two different roles: one only coordinates the metal atom and the other joins the coordination polymer into a 2-D sheet via N-H…O and C-H…O hydrogen bonds besides the coordination property. A blue photoluminescence peak at 435 nm was observed in solid state at room temperature. CCDC: 227946. |
