Synthesis, Characterization and X-Ray Structures of Catena Triphenyltin(iv) Benzenesulphonate, Catena -Trimethyltin(iv) Methylphosphonate and Catena-Trimethyltin(iv) Phenylarsenate

Talatisamine, a C19-diterpenoid alkaloid from Chinese traditional herbal `Chuanwu'

“…(Evans & Karpel, 1985;Kapoor et al, 2005;Zhang et al, 2006;Yin & Wang, 2004;Gielen et al, 1995). In the scope of our research work on the coordination ability of oxyanions (Diop et al, 2002, Diallo et al, 2009Diop et al, 2003) and our interest to synthesize new organotin derivatives for biological tests, we elucidate here the structure of the title compound, [C 15 H 21 O 6 P 2 Sn,C 12 H 24 N] (Fig. 1).…”

“…The crystal structure of the molecule is shown in Fig 2: hydrogen bonds between pairs of [SnMe 3 (PhPO 3 H) 2 ]generate a six membered ring, comprise a honey comb network by virtue of the hydrogen bonds between the ligands as in catenatrimethyltin(IV)phenylarsenate, reported by Diop et al (2002).…”

A two-dimensional silver(I) coordination polymer constructed from 4-aminophenylarsonate and triphenylphosphane: poly[[(μ3-4-aminophenylarsonato-κ3N:O:O)(triphenylphosphane-κP)silver(I)] monohydrate]

“…Metal organoarsonates are expected to display similar structural chemistry to metal phosphonates, but the obviously larger ionic radius of As 5+ (0.335 Å ) compared with P 5+ (0.17 Å ) and the somewhat weaker acidity of organoarsonic acid could lead to some novel architectures with different physical properties (Xie et al, 2010). In contrast with the attention received by metal phosphonates, studies of metal organoarsonates are still scarce and most of the reported metal organoarsonates are polyoxometallates (POMs) based on vanadium (Breen & Schmitt, 2008), molybdenum (Burkholder et al, 2003;Liu et al, 1988;Barkigia et al, 2002) and tungsten (Johnson et al, 2002) with discrete structures, although a handful of one-or twodimensional structures have also been reported (Burkholder et al, 2003;Reddy et al, 2006;Diop et al, 2002). An effective synthetic method for the design of various metal organoarsonates is the introduction of a variety of functional groups ISSN 2053ISSN -2296 # 2015 International Union of Crystallography such as carboxylate, amino or hydroxy groups, to the organoarsonic ligands.…”

Synthesis, spectroscopic characterization and crystal and molecular structures of phenylphosphonato SnR3 (R=Ph, Me) derivatives

“…Numerous studies on organotin(IV) complexes have been carried out in order to determine its biological properties against bacteria, fungi and cancer cell lines (Teoh et al, 1997;Crouse et al, 2004). Reports on structure determinations or spectroscopic characterizations of trimethyl-and triphenyltin(IV) derivatives with mono-and polybasic oxyanions (XO m n -; X = Cr, Se, S, As; m = 3, 4; n = 1, 2, 3) show that the oxyanions behave mainly as polydentate ligands involving a onedimensional polymeric, bi-or tridimensional network structure (Molloy et al, 1989;Diop et al, 2002;Diass é -Sarr et al, 2004;Fall et al, 2010;Boye et al, 2012). These triphenyltin(IV) or trimethyltin(IV) derivatives or complexes exist as monomers or polymers with a fivecoordinated tin(IV) atom.…”
