Synthesis and structural characterization of several tris(2-methyl-2-phenylpropyl)tin carboxylates containing germanium

Some tricyclohexyltin carboxylates containing germanium: synthesis, spectral and crystallographic characterization

“…The data are in consonance with similar types of compound previously reported. 6,13 In 1-6, the GeCH is a chiral centre, the CH 2 is a prochiral centre and the unit GeCHCH 2 comprises three hydrogen atoms that appear as two multiplets in the regions of 3.38-3.80 and 2.34-2.93 ppm. 9 The two (diastereotopic)…”

“…1 6,20 lie in the range 3.11(4)-3.269(3)Å. The carbonyl group C(19) O(2), which is sterically hindered by the three cyclohexyl groups attached to the tin atom and by the germyl substitution in the carboxylate group, prevents the carbonyl oxygen from approaching the tin in the neighbouring molecule to form an associated polymeric structure.…”

“…21,22 The comparable structure is that of Ph 3 GeCH(o-C 6 H 4 Cl)CH 2 COOSn(CH 2 (CH 3 ) 2 CPh) 3 , in which tin also possesses tetrahedral geometry. 6 The crystal structure of (p-CH 3 C 6 H 4 )GeCH(C 6 H 4 OCH 3 -p)CH 2 CO 2 Sn(C 6 H 11 ) 3 ·H 2 O (2) is given in Fig. 2.…”

Synthesis, characterization, and biological effects of diorganotin(IV) derivatives of substituted germyl propionic acid and crystal structure of 3‐triphenylgermyl‐3‐P‐fluorophenyl propionic acid

“…The values of the compounds range from 2.87 to 2.94 mms −1 , indicating that the complexes are hexacoordinated with a cis C 2 SnO 4 geometry around tin atom in the solid state [20]. The σ values fall in the range of 0.83-0.86 mms −1 .…”
