Tin Organometallic Compounds: Classification and Analysis of Crystallographic and Structural Data: Part 1. Monomeric Derivatives

“…There are two crystallographically independent molecules, differing by degree of distortion, in only two examples [738,739].…”

“…None have seven monodentate ligands, but one example [728] has five monodentate plus a bidentate ligand, another [745] has four monodentate and one tridentate ligands. Other examples have three bidentate and one monodentate ligands [190,542,720,[721][722][723][724][739][740][741], two bidentate plus three monodentate [725][726][727][729][730][731][732]735,736,748] and two monodentate plus one pentadentate [733,734,737,[742][743][744]746,747], 118 Brought …”

Mono-organotin(IV) and tin(IV) derivatives of 2-mercaptopyridine and 2-mercaptopyrimidine: X-ray structures of methyl-tris(2-pyridinethiolato)tin(IV) and phenyl-tris(2-pyridinethiolato)tin(IV)�1.5CHCl3

“…(16). 27,28 It seems noteworthy that in contrast to 1 and 5, in which all SPy ligands are bidentate rendering tin heptacoordinated, in Sn(SPy) 4 · 2H-SPy only two of the four SPy ligands are bidentate and tin as center of the molecular unit 23 is only hexacoordinated. 24 In accordance with the spectroscopic results (vide infra) it is evident that the thiol-thione equilibria of HSPy and HSPym [29][30][31][32] (Fig.…”

Novel organotin(IV) compounds derived from bis(organostannyl)methanes: Synthesis and crystal structures of bis[diphenyl(pyridin-2-onato)stannyl]methane and bis[bromophenyl(pyrimidine-2-thionato)stannyl]methane·C7H8

“…A number of organotin compounds with thiolates has been synthesized and studied for their biocidal [10] and antitumour [11] activities, while their catalytic activity in regioand stereoselective syntheses of c-diketones as well as a,b-dihydroxy ketones [12,13] have also been reported. Although many organotin compounds containing a single tin atom with pyrimidine-2-thiolate or pyridine-2-thiolate moieties and their derivatives have been structurally characterized [14][15][16][17][18][19][20][21][22][23][24][25][26], there are very few reports on the synthesis of organotin compounds containing more than one tin atom and thioles [25][26][27]. On the other hand, pyridinonebased ligands have been studied in view of their use as controlling reagents for the level of metals in body and in clinical diagnosis and chemotherapy [28,29].…”
