Reactions of SbCl(3) and BiCl(3) with M'Se-C(5)H(3)(R-3)N (M' = Li or Na; R = H or Me) gave homoleptic selenolate complexes of the general formula [M{Se-C(5)H(3)(R-3)N}(3)] (M = Sb or Bi). The complexes were characterized by elemental analysis, UV-vis and NMR ((1)H, (13)C and (77)Se) spectroscopy. The single crystal X-ray analysis of [M{Se-C(5)H(3)(Me-3)N}(3)].nH(2)O (M/n = Sb/1.5 and Bi/0.5) revealed that the antimony complex adopts a trigonal pyramidal configuration with monodentate selenolate ligands while the bismuth analogue acquires a distorted square pyramidal configuration defined by two chelating and one monodentate selenolate groups. Pyrolysis of [M{Se-C(5)H(3)(Me-3)N}(3)] either in a furnace or in hexadecylamine (HDA) at different temperatures gave a variety of M(2)Se(3) nanostructures. Thin films of metal selenides have also been deposited on glass substrate by aerosol-assisted chemical vapor deposition (AACVD). Both nanostructures and thin films of metal selenides were characterized by UV-vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM).

“…While our previously reported Rh/Sb complexes combined Sb with a potential d 8 /d 6 system, we were aiming at the synthesis of Pt/Sb complexes by the reaction of Sb(pyS) 3 with low-valent Pt compounds, thus equipping the heteronuclear complexes with a d 10 /d 8 TM. Indeed, the reaction of Sb(pyS) 3 with [Pt(PPh 3 ) 4 ] in tetrahydrofuran (THF) afforded the complex [(κ S -pyS)Sb(μ-pyS) 2 Pt(PPh 3 )] ( 1 ) in good yield (Scheme ).…”

“…), similar to those found in 2 (2.36 and 2.37 Å). The Sb···N separation, which involves the κS-bound pyS moiety of 1 (3.32 Å), is, because of the higher coordination number (CN) of Sb in 1 (CN = 4), significantly longer than that in Sb(pyS) 3 (2.84 Å; CN = 3) . Hence, additional coordination ([4 + 1] coordination) by the N atom of the otherwise dangling pyS ligand is only marginal.…”

“…Furthermore, all solvents were routinely degassed using three freeze–pump–thaw cycles, although the use of dry and oxygen-free solvents is not necessary for all reactions. [PtCl 2 (PPh 3 ) 2 ], Sb(pyS) 3 , PhSb(pyS) 2 , [PtCl(pyS)(PPh 3 )], and PhICl 2 were synthesized according to literature protocols. All other chemicals were commercially available and were used as received.…”

In the course of our investigations of the coordination chemistry of trivalent antimony (Sb) compounds, we studied heteronuclear complexes formed in reactions of the compounds RSb(pyS) 2 (R = pyS, Ph; pyS − = pyridine-2-thiolate) with [Pt(PPh 3 ) 4 ], i.e., complexes [(R)Sb(μ-pyS) 2 Pt-(PPh 3 )] (R = pyS, 1; R = Ph, 2). The reaction of 1 with o-chloranil proceeds cleanly with elimination of 2,2′-dipyridyl disulfide and formation of the salt), which features the cation 3 + . The charge-neutral, unsymmetrically substituted compound [(PPh 3 )Pt(μ-pyS) 2 Sb(μ-pyS) 2 Pt(κS-pyS)] ( 4) can be accessed by the reaction of 3 + with LipyS. The oxidation of 2 with o-chloranil furnishes the complex [(κ-O,O-C 6 Cl 4 O 2 )PhSb(μ-pyS) 2 Pt(PPh 3 )] ( 5). The oxidation of 1 with PhICl 2 afforded the paddlewheel-shaped complex [Sb(μ-pyS) 4 PtCl] (6). Moreover, compound 6 was obtained by the reaction of Sb(pyS) 3 with [PtCl(pyS)-(PPh 3 )]. The polarization of Pt−Sb bonds of compounds 1−6 was investigated by natural localized molecular orbital (NLMO) calculations, which suggest X-type ligand character (covalent Pt−Sb bonds) for 1 and 2, whereas the Sb ligand of 6 reflects Z-type character (dative Pt→Sb bonds). In 3 + , 4, and 5, high contributions of the reverse, i.e., L-type (dative Pt←Sb bonds), were observed. In conjunction with the results of NLMO analyses, 121 Sb Mossbauer spectroscopy proves that complexes 1−6 represent essentially trivalent Sb complexes with either a free lone pair (LP) at the Sb atom (1, 2, and 6) or LP character involved in L-type Pt←Sb coordination (3 + , 4, and 5).

“…Crystallographic investigations have shown that the thione I coordinates exclusively via the S atom [3]. In contrast, the thiolate of II can adopt a variety of coordination modes, namely: (i) S unidendate [2]; (ii) S,Nchelating [2, 3 c, 4]; (iii) S,N-bridging [3 c, 5] and (iv) S unidentate (with a weak M´´´N interaction) [6].…”

The reaction of [(Ph 3 P) 2 CuCl] 2 with 4-amino-6methyl-1,2,4-triazine-thione-5-one (AMTTO, 1) in methanol and further recrystallization from methanol/acetone solution gives [(C 4 H 4 N 3 SON(=CMe 2 )Cu(PPh 3 ) 2 Cl] (2) as a neutral complex.[(C 4 H 4 N 3 SON(=CMe 2 )Ag(PPh 3 ) 2 ]NO 3 (4) can be obtained in excellent yield by the reaction of [(AMTTO) 2 Ag]NO 3 (3) with triphenylphosphane in methanol/acetone.
