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

Synthesis, structure and cytotoxicity studies on diorganotin (R = Me, Et) complexes of N-methylpyridoxine (MePN, PN = Vitamin B6) containing different anions

“…The s parameter is 0.34 in compound 6 and this shows a coordination polyhedron slightly closer to a tpb than that of 1. 177.509 (18) ] are close to those found in 1 and are again in the range for essentially symmetric and linear triiodide ions. This ion is now hydrogen bonded (this bond does not significantly affect the structural parameters) to the CH 2 eOH of the MePN fragment and is packed in the crystal as shown in Fig.…”

Synthesis and structural studies of dimethyltin(IV) 5-[(E)-2-(aryl)-1-diazenyl)quinolin-8-olates

“…In 6, the asymmetric unit contains one molecule of the mononuclear Sn-complex plus one disordered molecule of toluene. The Sn is five-coordinate (figure 2) and the compound assumes a similar geometry to that observed for its dibutyltin(IV) analogue; the geometric parameters are also very similar [6]. The coordination geometry is best described as distorted cis-trigonal …”

“…Structural information on R 2 SnX(L) complexes is also available e.g. R = n Bu; X = Cl, L = 5-[(E)-2-(4-methoxyphenyl)-1-diazenyl]quinolin-8-ol [6]. The chemistry and structural properties of organotin(IV) 5-[(E)-2-(aryl)-1-diazenyl]quinolinolate(s) have also been explored for mixed ligand complexes which provided some elegant structural architectures [6] (see scheme 1 (ii-viii)).…”

“…R = n Bu; X = Cl, L = 5-[(E)-2-(4-methoxyphenyl)-1-diazenyl]quinolin-8-ol [6]. The chemistry and structural properties of organotin(IV) 5-[(E)-2-(aryl)-1-diazenyl]quinolinolate(s) have also been explored for mixed ligand complexes which provided some elegant structural architectures [6] (see scheme 1 (ii-viii)). The literature contains no reports of structural characterization by X-ray crystallography of dimethyltin(IV) compounds with 5-[(E)-2-(aryl)-1-diazenyl]quinolinolate(s), except for a very old report involving the ligand precursor quinolin-8-ol (Ox), i.e.…”

Diorganotin(IV) Complexes of Methyl 2‐{[(E)‐8‐Oxo‐5, 8‐dihydroquinolin‐5‐ylidene]hydrazino}benzoate

“…Although the chemistry of organotin(IV) quinolin‐8‐olate has been known for a long time, the structures of only a few organotin(IV) quinolin‐8‐olate have been investigated so far. Among these, the diorganotin(IV) bis (quinolin‐8‐olate) group of compounds has received most attention with the crystal structure determinations of R 2 SnL 2 complexes, where R = Me,1 p ‐ClPh and p ‐MePh,2 n Bu and Cl,3 n Bu,4,5 t Bu,4 Ph,6,7 and Bz,8 revealing molecules with a highly distorted octahedral coordination of the tin atom by bidentate quinolin‐8‐olate groups and essentially cis ‐ R groups.
