(2,2'-Biquinoline-κ2N,N')chloro(2,2':6',2''-terpyridine-κ3N,N',N'')ruthenium(II) hexafluorophosphate, [RuCl(C18H12N2)(C15H11N3)][PF6]

Acetonitrile(1,10-phenanthroline)(2,2′:6′,2′′-terpyridine)ruthenium(II) bis(hexafluorophosphate)

“…These values are in good agreement with those reported for iridium(III) and ruthe-nium(II) complexes of the terpy ligand (Yoshikawa et al, 2003;Spek et al, 1994). The ligand environment about the Ru atom is distorted octahedral; the terpy ligand is coordinated in a meridional fashion, the phen ligand is coordinated in a cis fashion and the N atom from the acetonitrile molecule is trans to one of the phen N atoms.…”

(2,2′-Bipyridine-κ2N,N′)chlorido[4′-(2,5-dimethoxyphenyl)-2,2′:6′,2′′-terpyridine-κ3N,N′,N′′]ruthenium(II) hexafluoridophosphate acetonitrile monosolvate

“…The Ru-N distances are in the range of 2.036 (2)-2.084 (2) Å with the exception of the central Ru-N bond of the terpyridyl ligand, which is shorter [1.9503 (19) Å] as expected (Table 1). The Ru-Cl distance of 2.4096 (8) Å observed in this structure is similar to those found in other ruthenium(II)-terpyridine-chlorido complexes (Spek et al, 1994;Fujihara et al, 2003;Tseng et al, 2008). The pendant dimethoxyphenyl substituent is not coplanar with the terpyridyl moiety; the dihedral angle between the central pyridyl and the dimethoxyphenyl ring is 46.72 (11)°.…”

Photoisomerization and thermal isomerization of ruthenium aqua complexes with chloro-substituted asymmetric bidentate ligands

“…The X-ray crystallographic data, and selected bond lengths and bond angles are summarized in Tables S1, † 1, and 2, respectively. For the ruthenium chloro complexes p-1Cl, 3Cl, 4Cl, the bond lengths and angles around the ruthenium center are similar to those reported by Reedijk et al 19 for [Ru(tpy)(2,2 0 -biquinoline)Cl] + rather than those of derivatives of [Ru(tpy)(2,2 0 -bipyridine)Cl] + . 20 This similarity arises because of steric repulsion between a chloro ligand and pendant moieties of pyqu derivatives; this is conrmed by the distances between H28 and Cl1 (2.42-2.57Å).…”
