Crystal structure of triphenyl(5-mercapto-1-phenyl-1,2,3,4-tetrazolato)tin(IV)

Investigation on coordination modes of organotin(IV) complexes with 6-thiopurine and related ligands

“…2.474(3)-2.614(5) Å [11,22]. The Sn-N bond lengths are markedly shorter [Sn(1)-N(3) 2.718 (6) Å ] than those reported in diorganotin derivatives of 1-phenyl-1H-tetrazole-5-thilato (2.975(5) [22c] and 2.947(4) Å [23]), all of which lie within the sum of their respective van der Walls radii (3.74 Å ) [24].…”

“…The Sn(1)-S(1) bond length (2.447 (2)Å) is almost equal to that of complexes 1 and is longer than that in Ph 3 Sn(Me 2 Pymt) (2.433Å) [24], within the range (2.405-2.481Å) for triphenyltin(IV) thiolates compounds R 3 SnL reported before [25,26]. The Sn(1)-N(1) bond length (3.009Å) is shorter than those in Ph 3 Sn(MBZ) (3.07Å) [14] and Ph 3 Sn(MNBT) (3.14Å) [27] but longer than that in complex 1 (2.878Å) and complex Ph 3 Sn(Me 2 Pymt) (2.835Å) [24].…”

“…In addition, there is a weak intramolecular Sn N interaction, the Sn(1) N(1) bond length (3.072(4)Å) is longer than the sum of covalent radii (2.15Å), but is considerably shorter than the sum of van der Waals radii of Sn and N atoms (3.74Å) [29]. This bond length is almost equal to that in Ph 3 Sn(MBZ) (3.07Å) [30], but is shorter than that of triphenyl-(5-mercapto-1-phenyl-1,2,3,4-tetrazolato) tin(IV) (3.28Å) [31] and is little longer than that reported in Ph 3 Sn(Me 2 dmt) (2.835(7)Å) [32]. Thus, complex 2 has a distorted cis-trigonal-bipyramidal geometry with the sulfur (S(2)) atom and two carbon atoms (C(10)) and (C(16)) occupying the equatorial plane, whereas • .…”
