摘要：

An organically templated manganese phosphate, Mn-6(H2O)(2) (HPO4)(4)(PO4)2 .C4N2H12.H2O, has been synthesized hydrothermally and characterized by synchrotron powder X-ray diffraction, thermogravimetric analysis, and magnetic measurements, The compound is structurally closely related to both a magnesium phosphate and an iron phosphate, and crystallizes in the triclinic space group P-1 (No, 2) with a = 12.81926(12) Angstrom, b = 15,87361(20) Angstrom, c = 6.47912(7) Angstrom, a = 99.8660(11)degrees, beta = 90,3913(10)degrees, gamma = 103.4265(9)degrees, V = 1261.928(25) Angstrom (3), and Z = 2, The structure consists of anionic sheets of manganese phosphate separated by piperazinium cations and water molecules, The basic building unit of the inorganic layers is a hexamer of edge-sharing Mn polyhedra. Magnetic susceptibility measurements and bond valence calculations confirm the assignment of high-spin Mn2+ (d(5)) in the title compound. (C) 2001 Academic Press.
