摘要
A 2D copper coordination polymer of [Cu2(3-PyOH)2(EDTA)]n (EDTA4-=ethylenediaminetetraacetate quadrivalent anion C10H12N2O8, 3-PyOH=3-hydroxypyridine) was synthesized and characterized by the element analysis, IR and single crystal X-ray diffraction. The title complex crystallizes in monoclinic system with space group P21/c, a=1.3275(3) nm, b=0.93039(19) nm, c=0.94844(19)nm, β=108.21(3)°, and V=1.1128(4) nm3, Z=2, R=0.0252, wR=0.0661. Each copper(Ⅱ) atom is five-coordinated by three O atoms and one N atom from two different EDTA4-groups and one N atom from 3-PyOH ligand, forming a distorted square-pyramidal coordination geometry. Two adjacent copper(Ⅱ) atoms are bridged by the bis-tetradentate EDTA4- groups, constructing a two-dimensional layer structure along bc plane. The adjacent Cu…Cu distances are 0.5025(3) and 0.6113(3) nm.
A 2D copper coordination polymer of [Cu2(3-PyOH)2(EDTA)]n (EDTA4^-=ethylenediaminetetraacetate quadrivalent anion C10H12N2O8, 3-PyOH=3-hydroxypyridine) was synthesized and characterized by the element analysis, IR and single crystal X-ray diffraction. The title complex crystallizes in monoclinic system with space group P2 1/c, a=1.327 5(3) nm, b=0.930 39(19) nm, c=0.948 44(19) nm, β=108.21(3)°, and V=1.112 8(4) nm^3, Z=2, R =0.025 2, wR =0.066 1. Each copper(Ⅱ) atom is five-coordinated by three O atoms and one N atom from two different EDTA^4- groups and one N atom from 3-PyOH ligand, forming a distorted square-pyramidal coordination geometry. Two adjacent copper(Ⅱ) atoms are bridged by the bis-tetradentate EDTA^4- groups, constructing a twodimensional layer structure along bc plane. The adjacent Cu…Cu distances are 0.502 5(3) and 0.611 3(3) nm. CCDC: 618806.
