Coordination compounds of indium. Part 43. Indium(III) derivatives of benzenethiol, and the crystal structure of tetraphenylphosphonium bromotris(benzenethiolato)- indate(III), Ph₄P[BrIn(SPh)₃]

Abstract

, 804 (1987) In(SPh), is readily prepared by the reaction of InCl, and NaSPh in methanol. The compound is a Lewis acid, forming 1:1 adducts with 2,2'-bipyridine, 1, 10-phenanthroline, N, N, N', N'-tetramethylethanediamine, bis(diphenylphosphino)ethane, and dimethylsulphoxide, and 1:2 adducts with pyridine, trimethylamine, and triphenylphosphine. Reaction with R4NX (X = C1, Br, I) or similar salts gives R4N[XIn(SPh)3] salts, which are 1:l electrolytes. The structure of Ph4P[BrIn(SPh),] has been determined by X-ray methods: The crystals are monoclinic, space group P2,/c, with cell dimensions a = 9.964 (3) [Traduit par la revue]

Thiosemicarbazone Complexes of Indium with New Modes of Coordination: X-ray Crystal Structure of {(Me2In)2[NC5H4CMeNNC(S)NC6H5]2}(InMe)

“…A THF molecule is included in the cavity of 3 . The In(1)−S(11) distance (2.491(2) Å) in 3 is comparable to those found in the tris-chelate complex of indium [In(2-C 5 H 4 NS) 3 ] (2.531(2) Å), In(SPh) 3 ·2py (2.458 Å), and K 8 (In 4 S 10 ) (2.453−2.479 Å), In(SMes*) 3 (2.403 Å), and Ph 4 P[BrIn(SPh) 3 ] (2.435−2.470 Å) . The In(1)−N(9) distance (2.394(4) Å) is very similar to that in MeIn(C 6 H 5 CH 2 NNC 5 H 4 ) 2 (2.349(3) Å) and InCl(BTA-TM) (2.322(10) Å) .…”

“…The literature reveals many other structural reports of neutral five-coordinate organoindium complexes with trigonal-bipyramidal coordination. , Of these complexes, a few organoindium complexes have had square-pyramidal coordination . The unusual arrangement observed for 3 is similar to that recently reported for the monomeric structure of MeIn(C 6 H 5 CH 2 NNC 5 H 4 ) 2 …”

Synthesis and Characterization of Indium Compounds with Phosphinothiol Ligands. The Crystal and Molecular Structures of [In{2-(Ph2P)C6H4S}3], [In{2-(Ph2P)-6-(Me3Si)C6H3S}2{2-(Ph2PO)-6-(Me3Si)C6H3S}], and [NMe4][In{PhP(C6H4S-2)2}2]·CH3CN

“…The coordination chemistry of indium thiolates remains relatively unexplored with only a handful of compounds exhibiting In−S bonds having been structurally characterized. , Since the pronounced tendency of sulfur to bridge metal centers often produces insoluble polymers, one strategy for the synthesis of low molecular weight compounds exploits bulky substituents on the ligand to prevent the association process. This approach has proved successful in the preparation and structural characterization of dinuclear indium thiolates of the class [Mes 2 In(μ-SR)] 2 (R = Bu t , 2-Bu t C 6 H 4 , or SiPh 3 ), which show potential as precursors for the deposition of indium chalcogenides under MOCVD conditions.…”

Indium Tris(alkylthiolate) Compounds

“…2,6,7 In contrast it appears that the only known indium tris(alkylthiolate) compounds are In(SEt) 3 , In(S-n-Bu) 3 , and In(SCMe 2 Et) 3 , which Tuck and co-workers synthesized by electrochemical methods. 3 The anions [In(SPh) 3 Br] -, 5 [In(S-t-Bu) 4 ] -, and [In(SCH 2 CH 2 S) 2 ]have also been prepared and structurally characterized. 8 We recently reported the syntheses of the homoleptic indium amide complexes In(NRR′) 3 (R ) Ph or t-Bu, R′ ) SiMe 3 ; R ) t-Bu, R′ ) SiHMe 2 ).…”
