two-dimensional manganese(ii) coordination polymer complex containing aqua, diethyl phosphate and chloride ligands: synthesis, spectroscopic characterization, thermal analyses, and crystal structure

A new two-dimensional manganese(ii) coordination polymer, [mn(μ-dep)(μ-cl)(h2o)2]n (1) (dep is diethyl phosphate), was prepared from the reaction of mncl2.4h2o and tep (tep is triethyl phosphate) ligand in mixture of h2o/ch3oh (1:10) at 40 °c. suitable crystals of this complex for crystal structure determination were obtained by slow evaporation of the produced colorless solution at room temperature. complex 1 was characterized by elemental analysis, ir spectroscopy and single-crystal x-ray diffraction. the x-ray structural analysis indicated that the manganese(ii) is six-coordinated in a distorted octahedral configuration by four oxygen atoms from two water and two bridged diethyl phosphate ligands and two bridged chloride anions. also, the thermal stability of 1 was studied by thermogravimetric and differential thermal analyses.
