Complexes of zinc halides and nitrate with aniline, p-nitrosodimethylaniline and p-nitrosodiethylaniline have been synthesized and characterized by their magnetic, spectral and conductance measurements. The complexes absorb strongly around 425#x2013;435 nm in methanol while their mull spectra had one strong band in the range 445#x2013;490 nm. Their conductance data in nitromethane show that they are non-electrolytes. However, they have appreciable molar conductance in methanol due to solvent interaction. The nitrosodialkylanilines are presumed to bond through the oxygen of the nitroso group while aniline coordinates through the amino nitrogen. The magnetic data indicate that the complexes are diamagnetic and deviate from the additivity law. The halide complexes are tetrahedral while the nitrate complexes adopt either the square pyramidal or octahedral configurations.
