title: Hydrothermal Synthesis and Structure of Fe(NH(3))(2)PO(4): A Novel Monophosphate.
abstract: Fe(NH(3))(2)PO(4) is synthesized under mild hydrothermal conditions in the presence of urea. The crystal structure is solved for powder X-ray diffraction data. The unit cell is orthorhombic, a = 10.1058(2) Å, b = 6.3676(2) Å, c= 7.5714(2) Å, space group Pnma, Z = 4. The structure consists of a three-dimensional network of FeO(4)N(2) octahedra and PO(4) tetrahedra linked by vertex sharing. Two crystallographically independent ammonia molecules are linked to the iron atom. This compound is the first three-dimensional solid structurally characterized containing Fe-NH(3) bonds.
