New nitrato-complexes, M2Ir(NO3)6(MK, Rb, Cs) and K2Pt(NO3)6, with extensive metal–nitrate π-bonding
Abstract
New anhydrous hexanitrato-complexes of iridium(IV) and platinum(IV) have been prepared; e.s.r. measurements on K2Ir(NO3)6 reveal a remarkably high (f π= 0.38) degree of iridium-nitrate π-bonding.
