Abstract

The crystal structure of the title compound, [Mn(C5H4NCO2)3],H2O, has been determined by single-crystal X-ray diffraction at 295 K and refined by least squares to a residual of 0.053 for 2234 'observed' reflections. Crystals are monoclinic, C2/c, a 30.50(2), b 8.387(8), c 13.903(7) Ǻ, β 94.15(3)°, Z 8. The geometry of the manganese environment displays a pseudo-tetragonal distortion, the axial atoms being nitrogen (Mn-N 2.254(6), 2.217(6) Ǻ). The equatorial atoms are at distances Mn-N 2.059(5) Ǻ, Mn-O 1.891(5), 1.908(5), 1.942(5) Ǻ, the latter being trans to the nitrogen. The occupancy of the water molecule site is 0.54(1).
