The Structure of Tri(cyclohexyl)tin Chloride between 108 and 298 K: A Compound in Which Molecular Dimensions Vary with Temperature

“…Molecules of several triaryltin chlorides bearing bulky substituents in the organic group ( 3b − 3e ) adopt Type A structures with linear ···Sn−Cl···Sn−Cl··· chains along threefold axes but the long Sn···Cl distances (4.37−5.43 Å) indicate that in these compounds there are no intermolecular bonds. , In contrast to that observed for the trialkyltin chlorides discussed in this paper, there is no correlation between Sn−Cl and Sn···Cl distances or C−Sn−C angles, and the packing is determined largely by interactions between the bulky aryl groups. The structure of the monoclinic form of Ph 3 SnCl ( 3a ) has been determined at both 298 and 110 K, but there are no significant differences between corresponding intramolecular dimensions at the two temperatures .…”

“…The best-established examples of the first category are the trimethyl ( 1a ) and tribenzyl ( 1b ) derivatives. The second category comprises the trialkyl compounds with bulky groups R, e.g., (Me 3 Si) 2 CH ( 2a ), PhMe 2 CCH 2 ( 2b ), and PhMe 2 SiCH 2 ( 2c ), and triaryl derivatives with R = Ph ( 3a ), − C 6 H 4 X (X = m- Me ( 3b ), p - t Bu ( 3c ) or m- OMe ( 3d) ) or 3,5-C 6 H 3 Me 2 ( 3e ) …”

Stabilizing, non-covalent interactions in the solid state structure of novel aryltin hydrides and halogenides

“…[1][2] These compounds serve as starting materials for the generation of aryltin halogenides (Ar n SnX 4-n ), which themselves act as major precursors for the formation of highly oxygen and temperature labile aryltin hydrides (Ar n SnH 4-n ). Hence, the majority of reported crystallographically studied aryl substituted tin species have been tetraaryl stannanes [3][4][5][6][7][8][9] and aryltin monochlorides [10][11][12][13][14][15][16][17][18][19] and dichlorides. [20][21][22][23][24][25][26][27] However, solid state examples of trichlorides are limited, and the only aryltin hydride species to have been characterized crystallographically is Mes 2 SnH 2 (Mes = 2,4,6-trimethylphenyl).…”
