Abstract
Two novel coordination polymers have been hydrothermally synthesized by reactions of Cu(II), Mn(II) salt with 2-carboxyethyl(phenyl)phosphinic acid (H2L), namely, [Cu(L)(H2O)]n (1) and [Mn(HL)2]n (2). Both compounds were well characterized by single crystal X-ray diffraction, elemental analysis, IR spectroscopic, power X-ray diffraction and magnetic studies. Compound 1 crystallizes in a noncentrosymmetric monoclinic Cc space group and presents an inorganic two-dimensional (2D) network, whereas compound 2 adopts a noncentrosymmetric Pca21 space group and exhibits a 2D layer structure. Magnetic studies reveal a dominant ferromagnetic interaction in 1, and weak antiferromagnetic coupling between the Mn(II) ions in 2 mediated by phosphinico group, respectively.
