Popis:	Iron(II) hippurate, Fe(hipp)/sub 2/(H/sub 2/O)/sub 3/ 2H/sub 2/O, has been prepared and characterized. Single-crystal x-ray diffraction revealed the compound to be essentially isostructural with the previously reported cobalt(II) and nickel(II) hippurates, crystallizing as a linear chain with canted metal octahedra bridged by the oxygen atom of a water molecule. The space group is C2/c with four formula weights per unit cell. The structural properties for the compound are a = 40.824 (7) A, b = 6.908 (1) A, c = 8.038 (1) A, and ..beta.. = 91.6 (1)/sup 0/; the intrachain Fe-Fe' distance is 4.017 A, with R = 0.136 for 529 reflections. A magnetic model assuming a one-dimensional Ising chain with a magnetic phase transition at 8.1 K is consistent with the observed powder magnetic susceptibility and temperature-dependent Moessbauer data. 7 figures, 2 tables.
