Unprecedented Coordination Mode Variation of Group 13 Metal–Alkyl Compounds Derived from Methyl Thiosalicylate

Abstract

The X-ray structure analysis of the alkylaluminum and -indium compounds derived from methyl thiosalicylate, Me 2 Al(SC 6 H 4 -2-CO 2 Me) and [Me 2 In(µ-SC 6 H 4 -2-CO 2 Me)] 2 , revealed that the intermolecular S···C(π) interaction between the Al-S thiolate units and the ester π-surface can effectively compete with the hypercoordinate sulfur-metal dative bond. The former compound exists as the noncovalently bonded

Synthesis and structural studies of Cu(i) methylthiosalicylate complexes and their catalytic application in thiol-yne click reaction

“…The analogous bidentate mode of bonding of the methylthiosalicylate ligand has been reported in its Al( iii ) and In( iii ) complexes. 59 The geometry around Cu( i ) is closer to a trigonal pyramid rather than a tetrahedron. Cu( i ) is slightly tipped away (by 0.340 Å) from the trigonal basal plane constituted by P1, P2, and S1 atoms.…”

A pentanuclear bimetallic complex of manganese(II) and aluminium(III) ions: tetra-μ2-iodido-iodidobis(μ3-2-methoxyethanolato)bis(μ2-2-methoxyethanolato)dimethyl(tetrahydrofuran-κO)aluminium(III)tetramanganese(II)

“…Alkylaluminum alkoxides have been investigated as components of Ziegler±Natta catalyst systems (Lin et al, 1999;Rhine et al, 1999;Sobota, 2004;Lewinski et al, 2005). To date, several heterometallic aluminium complexes have been synthesized and characterized (Evans et al, 1998;Sobota et al, 2000Sobota et al, , 2002Utko et al, 2004;Jerzykiewicz et al, 2006).…”

Aluminium, gallium, indium and thallium

“…180 [Me 2 In(SC 6 H 4 -2-COOMe)] 2 associates into dimers by means of {m 2 -S} bridging, in contrast to its Al analogue. 70 In an attempt to produce the first In-bridged ferrocenophane, {(LiC 5 H 4 ) 2 Fe} was reacted with the structurally characterised [(k 2 -psyl)InCl 2 ] 2 affording a product [{(k 2 -psyl)In} 2 (m-Cl) 2 {m 2 ,k 2 -(C 5 H 4 ) 2 Fe}] in which the cyclopentadienide rings are bridged not by a single atom but a {In 2 Cl 2 } moiety. 145 Mixed phenyl-pyrazolyl complexes adopted a dimeric configuration with the pyrazolyls as the bridges, as in [R 2 In(m,k 1 :k 1 -dbpz) 2 InR 2 ] (R ¼ Ph, Me), however the analogue with only one pyrazolyl ligand adopted a fluxional [Ph 2 In(m-dbpz) (m-Ph)InPh 2 ] structure.…”
