Abstract
The title complex triaqua (3-hydroxy-5-hydroxymethyl-2-methylpyridine-4-carboxaldehyde-3-methylisothiosemicarbazone-k(3), O-3, N-7 , N-10)Ni(II) nitrate ([Ni(PLITSC) (H2O)(3)](NO3)(2), 1) represents the second transition metal complex incorporating an isothiosemicarbazide-pyridoxal based Schiff base that has been crystallographically characterized. Complex 1 crystallizes in a P21/n space group, with lattice constants: a = 11.2254(1) angstrom, b = 12.9941(2) angstrom, c = 12.8663(2), beta = 96,7713(5)degrees, V = 1863.64(4) angstrom(3), Z = 4, F(000) = 1016, R-1 = 0.0681, wR(2) = 0.1201. The central Ni(II) cation is found in a six-coordinate octahedral geometry formed by the tridentate Schiff base ligand PLITSC and three water molecules. The identity of 1 was further confirmed by elemental analysis, IR spectra, and conductometric and magnetochemical measurements.
