Organometallic and organobimetallic complexes of platinum(II) containing 2,2′-bipyrimidyl: syntheses and spectroscopic characteristics

Preparations are described of several monometallic complexes (bipym)PtR 2 [bipym = 2,2′-bipyrimidyl; R = Me, CF 3 , Ph, 1-adamantylmethyl (adme); R 2 = (CH 2 ) 4 ] and bimetallic analogues R 2 Pt(μ-bipym)PtR′ 2 [R = R′ = CH 3 , C 6 H 5 , adme; R = CH 3 , R′ = Ph, adme, CF 3 ]. IR, 1 H NMR and UV/visible spectroscopic characteristics of the two modes of bipyrimidyl coordination are discussed.
