The reaction of 6-mercaptopurine-9-D-riboside (6-mpr) with K2PtCl4 and K2PtCl6 has been studied. The obtained complexes: Pt(6-mpr)26H2O(1a) andPtCl2(6-mpr)2CH3OH(2) have been characterized by elemental analysis, thermogravimetry, IR and multinuclear NMR (1H, 13C, 15N). Spectroscopic studies suggest that compounds (1a, 2) contain monodeprotonated ligands, which bind to platinum ion via S(6) and N(7). Far-IR spectra indicate the square-planar geometry for (1a) and octahedral geometry for (2).

A series of novel aluminum alkoxide derivatives, [Cp(Me)Al-m-OR]2, (where R = Me 1,Et 2, iBu 3, tBuCH2 4, iPr 5, tBu 6) has been prepared by reacting Me(Cl)AlOR with CpNa. All the compounds were characterized by multinuclear NMR, elemental analysis and molecular weight determinaion cryoscopically in benzene.

Copper(I) perfluorinated carboxylates complexes with bis(diphenylphosphine)methane (dppm) of general formula [Cu2(ž-dppm)3(RCOO)2] dppm, whereR=C2F5, C4F9, C6F13, C8F17, C9F19, have been prepared and characterized by vibrational, 31P CPMASNMRand 13C CPTOSSB NMR mass spectra in the solid state. 1H, 13C, 19F NMR and variable temperature 31P NMR spectra were measured in solution. Temperature variable 31P NMR spectra revealed at least three dimeric species in equilibrium. IR and mass spectra analyses suggest dimeric complexes with three bridging diphosphines and monodentate carboxylates in the solid state.
