The crystal structure of butylchlorobis(8-quinolinate)tin(IV)

Crystal and solution structures of di-n-butyltin(IV) complexes of 5-[(E)-2-(4-methoxyphenyl)-1-diazenyl]quinolin-8-ol and benzoic acid derivatives: En route to elegant self-assembly via modulation of the tin coordination geometry

“…Cl [3], n Bu [4,5], t Bu [4], Ph [6,7] and Bz [8] revealed molecules with a highly distorted octahedral coordination of the tin atom by bidentate quinolin-8-olate groups and essentially cis-R groups. Structural information on R 2 SnX(L) type complexes (e.g.…”

Synthesis, crystal structures, cytotoxicity and qualitative structure–activity relationship (QSAR) of cis-bis{5-[(E)-2-(aryl)-1-diazenyl]quinolinolato}di-n-butyltin(IV) complexes, Bu2Sn(L)2

“…7. The molecular structure of n Bu 2 Sn(L 7 ) 2 (7). Displacement ellipsoids are shown at the 50% probability level.…”

“…One of the butyl groups in 7 is disordered over two conformations. Two sets of overlapping positions were defined for central two methylene groups of the disordered butyl group and the site occupation factor of the major conformation refined to 0.776 (7). Similarity restraints analogous to those described for 3 were employed during the refinement.…”

“…Consequently, the structures of a few organotin(IV) quinolin-8-olates have been investigated by X-ray crystallography. The diorganotin(IV) bis(quinolin-8-olate) group of compounds has received the most attention and the crystal structures of R 2 SnL 2 complexes, where R = Me [5], p-ClPh and p-MePh [6], n Bu and Cl [7], n Bu [8], t Bu [8] and Ph [9], showed molecules with a highly distorted octahedral coordination of the tin atom by bidentate quinolin-8-olate groups and essentially cis-R groups. In addition, structural information on two other types, viz., R 2 SnLX (e.g.…”

8-oxyquinolinate and 8-oxyquinaldinate in silicon complex chemistry — a new face of old ligands

“…This simple bidentate chelating system proved to be variable regarding the coordination modes that can generally be expected at an octahedrally coordinated Si atom. Although several examples for molecular structures of hexacoordinate tin complexes with two 8-oxyquinolinate derived ligands are known [10][11][12][13][14][15][16][17], they do not vary significantly. They underline the special role of the combination of both the Si atom together with 8-oxyquinolinato ligands as a unit of surprising coordination properties, thus as a unit of special research interest.…”
