PREPARATION AND STUDY OF FUNCTIONALIZED 1,2,4-TRIAZINE DERIVATIVES OF THE (ETA(6)-ARENE)RU-II (ARENE=BENZENE OR P-CYMENE) AND (ETA(5)-C(5)ME(5))RH-III MOIETIES

摘要

In dichloromethane the complexes [{(eta(6)-arene)RuCl(mu-Cl)}(2)] (arene = benzene or p-cymene) and [{(eta(5)-C(5)Me(5)) RhCl(mu-Cl)}(2)] react with the triazines 4-amino-6-methyl-5-oxo-3 -thioxo-2,3,4, 5-tetrahydro-1,2,4-triazine (3-S-ATAZ), 4-amino-6-methyl-5-oxo-3-phenylamino-4,5-dihydro-1,2,4-triazine (3-PhNH-ATAZ) and 4-amino-6-methyl-5-oxo-3-amino-4,5-dihydro- 1,2,4-triazine (3-NH2-ATAZ) to form the corresponding complexes [(eta(6)-arene) RuCl(triazine)]Cl and [(eta(5)-C(5)Me(5)) RhCl(triazine)]Cl. The new compounds have been characterized by conductance measurements and spectroscopic (IR,H-1, C-13)methods. In every case the triazine acts as a chelating bidentate ligand, which has been confirmed by a single-crystal diffraction study carried out with [(eta(5)-C(5)Me(5)) RhCl(3-PhNH-ATAZ)]PF6 . H2O.
