cis-Chloridobis(4,4′-dimethyl-2,2′-bipyridine)nitrosylruthenium(II) bis(hexafluorophosphate)

Abstract

In the cation of the title complex, [RuCl(NO)(C12H12N2)2](PF6)2, the central RuII ion is sixfold coordinated by a chloride ion and a nitrosyl ligand, which are cis to one another, and by four N atoms of two 4,4′-dimethyl-2,2′-bipyridine ligands, in a slightly distorted octahedral geometry. One of the PF6 − anions is located in a general position, while the other is composed of two half PF6 − anions located on twofold rotation axes. The crystal packing is dominated by C—H...F hydrogen bonds, leading to the formation of a three-dimensional supramolecular structure. There are also C—H...Cl hydrogen bonds present.

Synthesis, Identification, and Biological Study for Some Complexes of Azo Dye Having Theophylline

“…In our case, the complexes did not show photoisomerization behavior which means that the CPAT dye is bonded to the metal within complex structure. It is nice to point that the cis isomer backed totally at room temperature to trans isomer which means that the chromic behavior is intrinsic [27][28][29][30][31][32].…”

Role of Coordination compounds as photosensitizes of photodynamic therapy :on overview

“…Therefore now a two-photon absorption technique is used which is nonlinear optic. The wavelength in this technic is double the wavelength in the case of absorption of one photon which permits to penetrate the light more in the tissue with less damage (Figure 2) [11][12][13]. The substituted boron dipyrrin (BODIPY) of selenophene (Figure 4) are good fluorophores and photosensitizers.…”
