“…Distortion isomerism are quite abundant in tin chemistry [174,175,187,188,190,262,330,331,428,202,566,608,652,661,663,664,690,691], with two derivatives existing in three isomeric forms [585,586,697]. The most common form of distortion isomerism [22] is where two or more crystallographically independent molecules are found within the same crystal.…”

“…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 …”

“…[3] A number of papers related to studies focused on organotin compounds that contain anisobidentate S,Odonor ligands are also available. [4] Compounds that contain thiocarbamate [5] and thio-β-diketonate [6] ligands were reported some time ago. Our early studies with thiocarboxylate ligands have revealed that the ligand may bind to the organotin center either monodentately through S or bidentately by using both O and S atoms.…”

A few organotin(IV) ([R2SnCl2], [R3SnCl]; R = Me, Ph, nPr, or nBu) and organolead(IV) ([Ph2PbCl2], [Ph3PbCl]) compounds that contain the thiophene‐2‐thiocarboxylate ligand have been synthesized and characterized by 1H, 13C, 119Sn NMR; FTIR; and UV/Vis spectroscopy. The molecular structures of some of the compounds were studied by single‐crystal X‐ray diffraction. Structures and electronic transitions have been explained on the basis of DFT calculations.

Tris-thiobenzoates, Arsenic, Antimony, BismuthTris-thiobenzoates o f arsenic, antimony and bismuth, M(SOCR)3 have been obtained from their oxides and characterized. In the X-ray crystal structure determinations of these, the group 15 atom and the three covalently bonded sulfur atoms are found to constitute a trigonal pyramid, the central atoms lie at a C3 axis. In the bismuth complex the thiobenzoate ligand tends to chelate. However, three comparatively short intermolecular M---S interactions are significant features for these molecules resulting in stacking of trigonal prisms providing an essentially six coordinate environment around arsenic and antimony and a nine-coordinate one for bismuth. The structure of PhSb(SOCPh)2 can be considered Metal carboxylates [1] are known to display in teresting structural features arising from the varying modes of bonding of the carboxylate anions. The monothiocarboxylates can be classified as asymetrical sulfur ligands [2] with the potential of bind ing metal ions depending upon their hardness and softness. Surprisingly, few metal thiocarboxylates [3 -5 ] have been prepared so far and even fewer ones [5-9] have been examined for structural de tails. Amongst group 15 elements, there are two reports on the structures of thioacetate complexes. In antimony tris-thioacetate [10] antimony is found to possess eight-fold coordination, and the resultant geometry is best described as a distorted dodeca hedron. A bidentate bonding pattern of the thioac etate group is also present in phenylantimony bisthioacetate [11] whose geometry is o f a distorted square-pyramidal shape.Our systematic efforts in main group metal com plexes of asymmetrical sulfur ligands such as thio-ß-diketonate [12-16] and thiocarbamate [17][18][19][20][21][22][23][24][25][26][27][28][29] have provided many discernible and interesting structural features.

Arsenic, antimony and bismuth oxides (Fluka) were used without further purification. PhSbCb and PhaSbCl were prepared by literature methods [21], as well as monothiobenzoic acid (b. p. 85 -87 °C/10 mm Hg) and potassium thiobenzoate [22], Sulfur was estimated by Messenger's method. IR spectra were recorded in the re gion 4000-400 cm-1 on a JASCO FT/IR-5300 spectrom eter on KBr disks. Elemental analyses were carried out on a Perkin-Elmer 240C model analyzer.
