Nitrogen containing Lewis base adducts of bis(O,O'-dialkylmonoselenophosphato)nickel(II) complexes of types, Ni{O(Se)P(OR)2}2(L)2 (where R = n-Pr, i-Pr; L = C5H5N, NC5H4Me-2, NC5H4Me-3) were synthesized by in situ reactions of NiCl2.6H2O, NaO(Se)P(OR)2 and corresponding Lewis base. The spectroscopic studies (UV-Vis, IR, 1H/31P NMR), revealed that these adducts has distorted octahedral geometry and central nickel(II) atom has bidentate coordination with monoselenophosphate moieties and Lewis base. Elemental analyses and magnetic moment results also support octahedral coordination of these adducts.
