Description	Mononuclear, square-planar platinum(II) complexes involving derivatives of aromatic cytokinins as the ligands, and having the general formula cis-[Pt(L-n)(2)Cl-2] (1-3) and trans-[Pt(L-n)(2)Cl-2] (4-6), where n = 13, L-1 = 2-chloro-6-(benzylamino)-9-isopropylpurine, L-2 = 2-chloro-6-[(4-methoxybenzyl)amino]-9-isopropylpurine and L-3 = 2-chloro-6-[(2-methoxybenzyl)-amino]-9-isopropylpurine, have been synthesized and characterized by elemental analysis, MALDI-TOF mass, FT IR, H-1, C-13, N-15 and Pt-195 NMR spectral measurements. Dynamic cis-to-trans isomerization process of complex 1 in N,N'-dimethylformamide (DMF) has been investigated by means of multinuclear NMR spectroscopy. The solid-state structures of 1, 4 center dot (DMF)(2), and 5 have been determined by single crystal X-ray analysis. X-ray structures revealed that the heterocyclic ligands are coordinated to platinum via nitrogen atom N(7) in all the complexes studied.
