Abstract :
The reaction of [{(h6-p-cymene)Ru(m-Cl)}2Cl2] with functionalized phosphine viz, diphenyl- 2-pyridylphosphine yielded complexes of the type: (a) P-bonded complex [(h6-p-cymene)RuCl2(PPh2Py)] (1), (b) P-, N-chelated complex [(h6-p-cymene)RuCl-(PPh2Py)]BF4 (2) and [RuCl2(PPh2Py)2] (3) resulting from the displacement of the p-cymene ligand. These complexes were characterized by 1H NMR, 31P NMR and analytical data. The structures of complexes 1 and 2 have been confirmed by single crystal X-ray diffraction study. Complex 1 crystallised in triclinic space group P1 ^ - with a = 10,9403 (3) ., b = 13,3108 (3) ., c = 10,5394 (10) ., a = 88,943 (2)°, beta equel117,193 (2)°, gamma = 113,1680 (10)°, Z = 2 and V = 123,39 (5) .3. The complex 2 crystallises in monoclinic space group P21 with a = 9,1738 (4) ., b = 14,0650 (6) s, c = 10,7453 (5) ., b = 106,809 (1)°, Z = 2 and V = 1327,22 (10) .3.
