Synthesis of novel bioactive phthalimido-4-methyl pentanoateorganotin(IV) esters with spectroscopic investigation

“…This mode of coordination with exo cyclic tin atoms results in penta coordination, trigonal bi-pyramidal geometry [25]. Such behavior of tetraorganotin(IV) compounds were reported by Pervez et al [6,17,18,21] as centro-symmetric skew trapezoidal bi-pyramidal geometry for the endo-cyclic tin status while the exo-cyclic tin status are in distorted trigonal bi-pyramidal geometry. The 119m Sn Mössbauer spectra displayed quadrupole splitting values over the range of 3.41 mm s À1 , which is greater than the 2.1 mm s À1 value reported in the literature [9,16,29] for a trans octahedral geometry around tin atom of monomer diorganotin dicarboxylate complexes Similarly, Gielen et al [15] reported trans octahedral geometry of monomer type compounds (Fig.…”

“…Both asymmetric and symmetric stretching of the phthalimido (C 2 O 2 N) and of the carbonyl (CO) groups and the stretching for Sn-C and Sn-O were exhibited as reported in the literature [16][17][18][19][20][21][22][23]. The asymmetric and symmetric stretching values of CO groups of monomeric as well in dimeric type esters were raised and lowered than the ligand's values and Dm values of compounds were higher than the Dm of ligand.…”

“…The ligand was prepared according to a reported procedure [21]. All the complexes were prepared according to reported procedures [8,9].…”

Synthesis and structure of functional spherosilicate building block molecules for materials synthesis

“…The four Si-O-Si cage edges parallel to the distortion axis accommodate this elongation by opening up the Si-O-Si angles around oxygen until they are close to linear (average Table 1 Crystal data and structure refinement for compounds I-III (5) 13.6919(5) b (Å ) 11.569 (3) 12.0644 (6) 26.567 (7) 14.1160(5) c (Å ) 13.258 (3) 12.3545 (6) 28.037 (7) 14.2380 (5) Si (4) Si (2) Si (1) Si (3) Sn (4) Sn (2) Sn (3) Sn ( Si (4) Si (2) Si (1) Si (3) Sn (4) Sn (2) Sn ( (2)-O(11) 2.799 Å ) to two tin atoms of trimethyl tin groups in the crystal and positioned trans to the terminal oxygens of the cage (Fig. 1) [62][63][64][65][66][67][68][69][70][71]. The three methyl groups are almost coplanar with the tin atom in each case producing a trigonal bipyramidal coordination geometry around tin.…”

Organotin esterification of (E)-3-(3-fluoro-phenyl)-2-(4-chlorophenyl)-2-propenoic acid: synthesis, spectroscopic characterization and in vitro biological activities. Crystal structure of [Ph3Sn(OC(O)C(4-ClC6H4)=CH(3-FC6H4))]

“…For example the structures of triorganotin carboxylates range from a discrete form to polymer chain as shown in Scheme 1 [3][4][5]. Keeping in view the structural and biological diversity of organotin(IV) carboxylates and in connection with our interest in coordination chemistry of organotin compounds with different carboxylic acids [6][7][8][9][10], here we present the synthesis, characterization and in vitro biological …”
