Abstract
The reaction of the dinuclear platina-β-diketone [Pt2{(COMe)2H}2(μ-Cl)2] (1) with two equivalents of adenine and its methylated derivatives N6-R,9-R′Ade–H resulted in adenine-based aminocarbene platinum(II) complexes [Pt(COMe)Cl{CMe(N6-R,9-R′Ade–H)-κC,κN}] (R/R′ = Me/Me, 2; H/Me, 3; H/H, 4) whose identities were confirmed by NMR and IR spectroscopies as well as by high-resolution mass spectrometric investigations. Single-crystal X-ray diffraction analyses of complexes 2 and 4·THF revealed relatively short Pt–C and N–C bonds in the aminocarbene–platinum units, which is in accord with a substantial double bond character of these bonds. The electronic structure of these complexes will be further confirmed by DFT calculations as also the course of reaction.
