Synthesis and crystal structure of bis(1-oxopyridine-2-thiolato)phenylbismuth

Abstract

The title compound, a principal product of the reaction of acetato(dipheny1) bismuth and sodium 1 -0xopyridine-2-thiolate, has been synthesised and its structure determined by X-ray crystallography from diffractometer data.Crystals are rnonoclinic, a = 21 .I 57, b = 8.81 3, c = 8.944 A, all *0.005 8, p = 96-74 f 0.05". space-group P2Ja. Z = 4. The structure was solved by Patterson and Fourier methods and refined by least-squares techniques to R 3.9% for 931 reflections. The co-ordination about the bismuth atom was found to be a distorted octahedron with a pair of electrons presumably occupying a co-ordination site. The sulphur and oxygen atoms are in a cisconfiguration.

“…The 13 C NMR spectra further provide support for the structure of the complexes. The d of the C atom (C]S) shifted to down filed after metallation (See Supporting Information Fig S3 and S4), which is due to the thione/thiol evolution (in which a C]S double bond changes to a more shielding C]N double bond [16]). …”

“…The C(25)-S(2) bond length is 1.739 Å, which is shorter than 1.82 Å for a C-S single bond and longer than 1.56 Å for a C＝S double bond. 21 The C-N bond distance, C(25)-N(2) 1.279 Å, conforms to the double bond [d(C＝N) 1.28 Å]. 21 The Pd-S distance, 2.250 Å, is in the range normally found in four-coordinate Pd(II) complexes of sulfur-nitrogen chelating agents.…”

“…21 The C-N bond distance, C(25)-N(2) 1.279 Å, conforms to the double bond [d(C＝N) 1.28 Å]. 21 The Pd-S distance, 2.250 Å, is in the range normally found in four-coordinate Pd(II) complexes of sulfur-nitrogen chelating agents. 8,22 The Pd-N distances are also comparable with the values found in most square-planar palladium(II) complexes of Schiff base ligands derived from thiosemicarbazid and S-alkyl esters of dithiocarbazic acid 8,22 and other N-substituted derivatives 11 of dithiocarbazates.…”

“…Because of the short distances (av. 2.939 Å)ofthe ligands, the coordination of the bismuth atoms is distorted from regular trigonal prism with angles within chelate rings of average 68°.The present complex exhibits Bi-Sbond lengths within the range from 2.646 to 2.749 Å with a mean value of 2.685 Å,shorter than in Bi(mpo)3 (2.808 Å), and Bi-Odistances within the range from 2.395 to 2.783 Å with a mean value of 2.622 Å,longer than in Bi(mpo)3 (2.480 Å), but close to those in [Bi(mpo)2Ph] [6], in which the Bi-Sand Bi-O bond distances are 2.674 and 2.525 Å,r espectively. The relatively short C-Sd istances (av.…”

“…Current interest in bismuth thiolates derives in part from their ability as fungicides, antitumor agents, nanoparticle synthesis and mechanism research of bioactivity [2][3][4][5]. Although Bi(III) compounds of the Bi(mpo) 3 and Bi(ph)(mpo)2 (Hmpo =2 -mercaptopyridine-N-oxide) have been prepared previously [6,7], X-ray structural data are available only for not-substituted base on the pyridine ring. The crystal structure of the title compound is adimer with heptacoordination for each bismuth imposed by three sulfur and four oxygen atoms.…”
