“…Their U.V. spectra recorded in non-polar solvents exhibit large bathochromic shifts indicative of N+Sn co-ordination and structure (1; R' = aryl), but which is absent in co-ordinating solvents as the weak N+Sn bond is replaced by a donor solvent molecule (solv) as in (2). Further, when the aryl group contains a donor group in the ortho position, the arylazobenzoato-group was postulated to function as a terdentate ligand, giving rise to structure (3).…”

“…where R = ZIIF0I -IFCII / ZIF0I and R w = [Iw(IF0l -IFCI)2 / ZwF0 2 ]In the IR spectrum of {Ph3Sn[02CC 6 H4(N = N(C6H3-4-OH-5-CHO))-o]OH 2 } the asymmetric carbonyl stretch is found at 1647 cm" 1 compared wnth 1733 cm" 1 for the uncoordinated 5-(2'-carboxyphenylazo)salicylaldehyde (hereafter LH); this result is typical for Sn-0 coordination in arylazobenzoates[15]. The 1 H NMR spectrum showed the expected resonances and integration for the formulation of the compound.…”

The crystal structure of the title compound, {Ph3Sn[C>2CC6H4(N=N(C6H3-4-OH-5-CHO))-o]OH2}, reveals the carboxylate group to coordinate the tin atom via one oxygen atom only [Sn-0 2.161(5) A], The tin atom is also coordinated by a water molecule [Sn-O 2.527(5) Ä] and exists in a trigonal bipyramidal geometry with the three phenyl groups in equatorial positions; the O-Sn-O axial angle is 176.3(2)°. The lattice is stabilised by Η-bonding contacts as well as charge-transfer interactions. Introduction. The chemistry of organotin carboxylates is of importance owing to the wide use of such compounds in a variety of applications [1-4]. For example, organotin carboxylates have been used as homogeneous catalysts and as biocides. More recently, the anti-tumour properties of this class of compound have been investigated [5]. Crucial to the understanding of how these compounds function is a knowledge of their structure and, as a consequence, a large number of crystal structure determinations of organotin carboxylates have been reported for which a rich diversity of structural motifs exist [6, 7], An additional donor atom(s) resident on the carboxylate residue also increases the range of structural possibilities and it has been noted that frequently Sn-N and Sn-0 interactions of this type may be found, in addition to the Sn-O(carboxylate) connectivities [6, 7]. As a part of a wider study designed to ascertain the reason(s) for the structural variation found in these systems, the title compound, {Ph 3 Sn[02CC6H4(N = N(C 6 H3-4-OH-5-CHO))-o]OH2}, has been prepared and characterised. The crystal and molecular structure of {Ph3Sn[0 2 CC6H 4 (N=N(C6H3-4-0H-5-CH0))o]} as the unsolvated [8] and solvated [9] forms have been reported.
