Hydrothermal synthesis, crystal structure, and magnetic property of a three-dimensional inorganic-organic hybrid material:: Mn(H2O)[HO3PCH2NH(CH2CO2)2]

A novel three-dimensional inorganic organic hybrid compound, Mn(H2O)[HO3PCH2NH(CH2CO2)(2)] from a hydrothermal reaction of Mn (II) ion with N-(phosphonomethyl)iminodiacetic acid (H(4)PMIDA) was reported. The compound crystallizes in the monoclinic P2(1)/n with cell dimensions of a = 5.215(5) Angstrom, b = 14.111(15) Angstrom, c = 12.727(12) Angstrom, beta = 93.646(16)degrees, V = 934.6(16) Angstrom(3), and Z = 4. In this structure each Mn atom is six-coordinated with the carboxylic groups and phosphonic groups to form layers along the bc plane. These layers are further connected with the organic moieties of H(2)PMIDA, resulting in a complicated three-dimensional network structure. Thermogravimetric analysis, IR spectrum and magnetic susceptibility of this compound are given. (C) 2004 Elsevier Inc. All rights reserved.
