摘      要：The novel copper(II) coordination polymer with 2-oxo-propionic acid be nzoyl hydrazone and hexamethylenetetramine ligands, {Cu( μ2-C10H8N2O3)( μ2-C6H 12N4)1/2}n (C10H8N2O32- is the dinegative ion of 2-oxo-propionicacid benzoyl hyd razone), has been synthesized and characterized by elemental analysis and IR spe ctroscopy. The crystal structure was determined by single crystal X-ray diffrac tion analysis. The results show that the crystal of the title coordination polym er belongs to monoclinic space group C2/c, the cell parameters are as follows: a =1.787 5(2) nm, b=0.730 93(9) nm, c=2.038 2(2) nm, β=92.890(2)°, and V=2.659 6 (5) nm3, Z=8, Dc=1.687 Mg·m-3, μ(Mo Kα)=1.659 mm-1, F(000)=1 384, R=0.031 1, wR=0.079 0 for 2 454 observed reflections (I2σ(I)) out of 2887 unique reflecti ons. In this copper(II) coordination polymer, each copper(II) ion is five-coordi nated with a geometry of distorted square-pyramid. Two oxygen atoms of the carbo xyl of each C10H8N2O32- acts as a bridge to bond two neighboring copper(II) ions , leading to an infinite one-dimensional chainlike coordination polymer. Each ch ain is linked by coordinated hexamethylenetetramines with its neighbors to form an infinite two-dimensional network structure. CCDC: 255347.
