Several new symmetric and asymmetric homo and hetero dinuclear complexes of the type [Cl(dppp)(NO)2M(μ-pyz)M'(NO)2(dppp)Cl][ClO4]2 and [Cl(phen)(NO)2M(μ-pyz)M'(NO)2(dppp)Cl][ClO4]2(M,M'= Mo or W; phen = 1,10-phenanthroline; dppp = 1,3-bis(diphenylphosphino)propane; pyz = 1,4-pyrazine) were synthesized in three-steps starting from [M(NO)2Cl2]n(M = Mo, W). The final products were purified by eluting it through silica gel column (2×20 cm) with acetone as the eluent. Characterization of these complexes and some related complexes was accomplished through UV-vis., 1H-NMR, 13C-NMR and IR spectroscopies as well as elemental analysis. The infrared spectra indicate that the NO groups occupy cis-positions of the octahedral. The 1H and 13C-NMR data for the new compounds revealed a dimeric structures with bridged pyz.
