چکیده
The title compound, C26H20N6BrRu(BF4), crystallizes in the centrosymmetric space group P2(1)/n and consists of discrete complex units. The Ru(II) ion is octahedrally coordinated to one 2,2':6',2"-terpyridine (tpy), one 2-(phenylazo)pyridine (azpy) and a Br atom in trans-axial position at a distance of 2.547(5)A. The shorter Ru-N (azo) distance (1.960(3)A) than the Ru-N(py) distance (2.061(3)A) signifies a strong pi-backbonding, which leads to a longer, N=N (azo) bond (1.304(4)A).

The title heteroleptic bis--terpyridine complex, [Ru(C(15)H(11)N(3))(C(17)H(11)N(3))](PF(6))(2)·2CH(3)CN, crystallized from an acetonitrile solution as a salt containing two hexa-fluoridophosphate counter-ions and two acetonitrile solvent mol-ecules. The Ru(II) atom has a distorted octa-hedral geometry due to the restricted bite angle [157.7 (3)°] of the two mer-arranged N,N',N''-tridendate lig...
