Synthesis, characterization and antitumor activity of some arylantimony triphenylgermanylpropionates and crystal structures of Ph3GeCH(Ph)CH2CO2SbPh4 and [Ph3GeCH2CH(CH3)CO2]2Sb(4-ClC6H4)3

Synthesis and in vitro antitumor activity of some triarylantimony di(N‐phenylglycinates)

“…The absorption bands can be assigned on the basis of earlier publications [9,11] and are listed in Table 2. The absence of a strong band in the 3500-3300 cm −1 region, due to ν(OH), indicates that deprotonation and coordination of the carboxylate group with antimony have occurred as expected.…”

“…In some cases it may have a coordination number of six [2,7] or seven [5,8,9,11]. The IR stretching vibration frequencies of carbonyl groups in organoantimony carboxylates are very important for determining their structure.…”

“…References describing synthesis, structures, and applications of R 3 Sb(O 2 CR ) 2 (R = alkyl, aryl) have appeared in the literature [1][2][3][4][5][6][7][8][9][10][11]. Bajpai and coworkers [1] considered that the biological activity of some organoantimony carboxylates was not significantly affected by the nature of the R groups at Sb.…”

“…However, Singhal and co-workers [3] found that the effect of the nature of R groups on the activity was relatively complex. The published data on the antitumor activity of these compounds, however, are limited [9,10]. In order to study the influence of amino acid ligands at Sb on their antitumor activity, we have prepared a series of triarylantimony(V) di(N-phenylglycinates).…”

Vibrational and Quantum Chemical Study of Triphenylantimony (V) Benzilate SbPh3 [O2CC (OH) Ph2]2

“…I N most of the organoantimony (V) compounds, the coordination number of antimony atom is five, whereas in some cases it may be six [1,2] or seven [3,4] also. The stretching vibrational frequencies of carbonyl groups in organoantimony carboxylates play vital role in the determination of their structures.…”
