Complexes of Platinum(II) Containing Neutral and Deprotonated 9-Methyladenine. Synthesis, X-ray Structures, and NMR Studies on the Cyclic Trimer cis-[L2Pt{9-MeAd(-H)}]3(NO3)3 and the Dinuclear cis-[L2Pt(ONO2){9-MeAd(-H)}PtL2] (NO3)2 (L = PMePh2)

Singlet ground-state geometry optimization of the monomer, four dimers, and the trimer of [Pt(bph)(CO)2], where bph = biphenyl dianion, was performed at the B3LYP level of density functional theory (DFT) with a mixed basis...
