DOCUMENT TYPE: Journal CA Section: 26 (Biomolecules and Their Synthetic Analogs) Section cross-reference(s): 6, 29, 33 Treatment of [{RuCl2(h6-arene)}2] (arene = p-cymene, C6H6) with adenine (adeH), 9-ethyladenine (9etade) and adenosine (aden) provides [{Ru(ade)(h6-p-cymene)}4](CF3SO3)4 (2), [{Ru(9etadeH-1)(h6-p-cymene)}3](CF3SO3)3 (3) and [{Ru(adenH-1)(h6-C6H6)}3](CF3SO3)3 (4).There are some reagents with their cas registry numbers 52462-29-0 and 186311-80-8 are used in this study. The structures of complexes 2 and 3 were established by x-ray structural anal. 2 Crystallizes in the tetragonal space group I41/a with a = b 15.870(2), c 35.710(7) ?, Z = 4; 3×1.5H2O in the monoclinic space group C2/c with a 35.985(3), b 13.094(2), c 28.406(3) ?, Z = 8. Common to 2-4 is the participation of N6 and N7 in a five-membered chelate ring, which leads to a characteristic upfield shift in the 1H NMR signal of the pyrimidine proton H2. The tetrameric complex 2 exhibits the m-1kN9:2k2N6,N7 coordination mode for the bridging adeninate ligands, the trimeric complexes 3 and 4 the m-1kN1:2k2N6,N7 mode for the 9-substituted derivs. .

At. coordinates are given. The hybrid Me2PCH2CH2SMe ligand is bidentate (k2P,S) forming a five-membered chelate ring. The complex cation has two chiral centers, i.e. on the Ru and S atoms, and the relative configuration is R*(Ru)S*(S). .
