Abstract: The title complex has been synthesized by the reaction of CuCl_2 with trimethyl phosphate. Its Infrared spectra from 4000 to 100 cm~(-1) were measured. The assignment of some absorption bands was discussed. It is found that the stretching vibrations of bridge groups O—P—O are divided into two groups according to tbeir bond length. The crystal structure of the complex has been determined from single crystal X-ray diffraction data. The crystals belong to monoclinic system, space group P2_1/c with cell parameters: a=1.0704(4), b=0.5093(2), c=1.9737(6) nm; β=96.23(3)°; V=1.0696(6) nm~3; Z=4, final R=0.044. Copper ion is coordinated to five nonester oxygen atoms to form a distorted square pyramid. The adjacent copper ions are connected by symmetric and non-symmetric bridge groups of O—P—O, forming an infinite one-dimensional chain coordination polymer.
