Synthesis and molecular structures of six-coordinate stannabicyclooctanes, ROOCCH2CH2Sn(S2CNMe2)(XCH2CH2)2Y (X = O, S; Y = O, S, NMe)

Tin dithiocarbamates: applications and structures

“…The axial positions in the distorted octahedral geometry are defined by the organic-carbon and amine-nitrogen atoms, derived from the OCH 2 CH 2 N(Me)CH 2 CH 2 O dianion. A distinct coordination geometry is found in the analogous compound, [MeO(O )CCH 2 CH 2 ]Sn(S 2 CNEt 2 )(SCH 2 CH 2 OCH 2 CH 2 S), [67] Fig. 14.…”

“…having the bulky cyclohexyl group. In the next two structures to be described, the two chlorides in RSn(S 2 CNEt 2 )Cl 2 [67] which has crystallographic mirror symmetry, Fig. 13, the sulfur atoms of a symmetrically coordinating ligand, forming rather long Sn-S bond distances, are each opposite an alkoxide-oxygen atom.…”

Chlorobis(N,N-diethyldithiocarbamato)(vinyl)tin(IV)

“…The angle between these axial groups, S(3)---Sn(1)---C(11), is 161.0 (2) °. The two dtc ligands in the present complex show a bidentate bonding mode; however, X-ray studies show that dtc ligands usually act in an anisobidentate manner in organotin(IV)-bis-dtc complexes, except for [PhSnCI(S2CNEt2)2] (Harrison & Mangia, 1976) and [CH3OOCCH2CH2SnCI(S2CNMe2)2] (Jung, Jeong & Sohn, 1990) in which four Sn--S bond distances 2.528 (6), Sn--S(2) 2.661 (7), Sn--S(3) 2.551 (5), Sn--S(4) 2.593(4); 2 standard reflections monitored every 98 reflections intensity variation: <5% Fig. 1.…”

Metallocanes of group 14 elements 2. Derivatives of tin (Review)

“…The synthesis of stannocanes containing potential bidentate ester and dithiocarbamate groups as substituents at the tin atom was realized in [38]. All the compounds were isolated with good yields (74-80%).…”
