Abstract

Treatment of cis-MCl(2)L(2) (L = phosphine or COD) with (OH)(2)C6H2-3,5-(NO2)(2)[3,5-dncH(2)], 2-NH2C6H4OH [amOH(2)] or 4-NO2C6H3(NH2)(2) [npdaH(2)] in the presence of base (dbu or triethylamine) gives Pt(3,5-dnc)(PR(3))(2) [PR(3) = PMePh(2) (1), PMe(2)Ph (2)] and Pt(amO)(PR(3))(2) [PR(3) = PMe(3) (3), PMe(2)Ph (4), PPh(3) (5)], and M(npda)(COD) [M = Pt (6), Pd (7)] and Pt(3,5-dnc)(COD) (8). The molecular structures of 2 and 5 have been determined by single-crystal X-ray diffraction. Compound 2 displays square planar coordination with the catecholate ligands forming overlapping ''dimer pairs'' with pi-pi and O...Pt interactions. In contrast, 5 has distorted square planar geometry together with marked differences between the Pt-P distances trans to the oxygen and nitrogen.
