RUTHENIUM(II) PHTHALOCYANINATES(2-) - SYN THESIS AND PROPERTIES OF ACIDO)(CARBONYL)PHTHALOCYANINATO(2-)RUTHENATE(II), [RU(X)(CO)PC(2-)](-) (X=CL,BR,I,NCO,NCS,N-3)

((n)Bu(4)N)[Ru(OH)(2)Pc(2-)] is reduced in acetone with carbonmonoxid to blue-violet [Ru(H2O)(CO)Pc(2-)], which yields in tetrahydrofurane w ith excess ((n)Bu(4)N)X acido(carbonyl)phthalocyaninato(2-) ruthenate( II), [Ru(X)(CO)Pc(2-)](-)(X = Cl, Br, I, NCO, NCS, N-3) isolated as re d-violet, diamagnetic ((n)Bu(4)N) complex salt. The UV-Vis spectra are dominated by the typical pi-pi transitions of the Pc(2-) ligand at a pproximately 15100 (E), 28300 (Q(1)) und 33500 cm(-1) (Q(2)), only fai rly dependent of the axial ligands. nu(C-O) is observed at 1927 (X = I ), 1930 (Cl, Br), 1936 (N-3, NCO) 1948 cm(-1) (NCS), nu(C-N) at 2208 c m(-1) (NCO), 2093 cm(-1) (NCS) and nu(N-N) at 2030 cm(-1) only in the MIR spectrum. nu(Ru-C) coincides in the FIR spectrum with a deformatio n vibration of the Pc ligand, but is detected in the resonance Raman(R R) spectrum at 516 (X = Cl), 512 (Br), 510 (N-3), 504 (I), 499 (NCO), 498 cm(-1) (NCS). nu(Ru-X) is observed in the FIR spectrum at 257 (X = Cl), 191 (Br), 166 (I), 349 (N-3), 336 (NCO) and 224 cm(-1) (NCS). On ly nu(Ru-I) is RR-enhanced.
