“…All the complexes, except complex R3 exhibited ν(O-H) of lattice water in the range 3562 to 3360 cm -1 , while complex R2 revealed a broad peak in the range 3207-3181 cm -1 assigned to the ν(O-H) of coordinated water. A peak around 1616 to 1612 cm -1 is assigned to ν(C=N) of benzimidazole moiety and ν(C=C) of benzimidazole and quinazoline ring of ligand which on complexation was shifted to 1631-1618 cm -1 indicating the coordination of the quinazoline derivative to the ruthenium(II) ion via the tertiary nitrogen of the benzimidazole moiety [37].…”

A series of ruthenium(II) carbonyl complexes of the types [RuCl2(CO)2L]2·nH2O {n = 1, L = L1, L3}; [RuCl2(CO)2(L)(H2O)]·nH2O {n = 1, L = L2, L4, L6 and n = 2, L = L7}; [RuCl(CO)2(L-H)(H2O)]2 {L = L5}; [RuCl2(CO)2]3(L)2 {L = L8} were synthesized where L is 6R-5,6- dihydrobenzoimidazo[1,2-c]quinazoline (R-Diq; R = phenyl: L1/furyl: L2/thiophenyl: L3/o or p-hydroxyphenyl: L4, L5/o or p- hlorophenyl: L6, L7/dimethylaminophenyl: L8). The Ru(II) complexes were characterized by elemental analyses, conductivity measurements, TGA, infrared, electronic, NMR and mass spectral techniques. An octahedral geometry around the metal ion was proposed for all the complexes and monomeric, dimeric and trimeric stereochemistry was suggested. The catalytic activity for few ruthenium(II) complexes towards oxidation of benzyl alcohol, hydroquinone and cyclohexanol was also investigated.

Several ruthenium(II) carbonyl complexes, of the type [RuCl2(CO)2L]∙nH2O {n = 1, L = L1, L2, L4, [RuCl2(CO)2(L)(H2O)]∙nH2O {n = 1, L = L3, L5, were prepared where L is 6-R-5,6-dihydrobenzoimidazo[1,2-c]quinazoline (R-Diq; R = ethyl: L1/ n or i-propyl: L2, L3/ n or i-butyl: L4, L5. The techniques used to identify them included elemental analysis, conductivity tests, TGA, infrared, electronic, NMR, and mass spectrometry. For all of the complexes, an octahedral geometry around the Ruthenium ion with monomeric and dimeric stereochemistry was proposed. Investigation of the catalytic activity of the complexes towards the oxidation of hydroquinone, cyclohexanol, and benzyl alcohol was carried out.
