ORGANOTIN DITHIOCARBAMATE CHLORIDES: X-RAY STRUCTURES OF n-BuSn(S2CNEt2)Cl2 AND n-BuSn(S2CNEt2)2Cl

“…Atom X V ζ U(eq) Sn (1) 2286 (1) (14) 1538 (19) 8364 (16) 477 (17) 125 (6) In contrast to the structure of 1, n-BuSn(S2CNEt2)2CI (2) possesses a simple distorted octahedral geometry about the tin. Both dithiocarbamate ligands are bidentate, but they are not in a trans geometry with respect to each other, unlike the two bidentate dithiocarbamates in Sn(S2CNEt2)4 [5], The longest Sn-S bond in 2 is the one trans to the Sn-CI bond [Sn(1)-S(1), 2.612(3) A] and this is significantly longer than the Sn-S bond trans to the butyl ligand [Sn{1 )-S(4), 2.561(4) A], Interestingly, one dithiocarbamate is close to being isobidentate (ASn-S = 0.026 A), whereas the other is less symmetrical (ASn-S = 0.066 A).…”

“…In contrast to a number of compounds possessing the formula RSn(S 2 CNR' 2 ) 2 X (X = halide) which are known [12][13][14][15], only one compound of the type RSn(S 2 CNR' 2 )X 2 has been structurally characterised [R = CH 3 OOCCH 2 CH(COOCH 3 )CH 2 -] [16,17], Thus, as part of our continuing study of tin dithiocarbamate complexes as precursors for the deposition of tin sulphide thin films, we have prepared the less symmetrical compound n-BuSn(S 2 CNEt 2 )CI 2 (1) as an electron-rich, sterically unencumbered organotin dithiocarbamate. Fortuitously, crystals of n-BuSn(S 2 CNEt 2 ) 2 CI (2), a known compound [12], were also obtained from the same synthetic procedure.…”

Crystal structure of n-butyl-chlorido-bis[N-sec-butyl,N-n-propyl-carbamodithioato κ 2 S,S′]-tin(IV), C20H41ClN2S4Sn

“…In continuation of ongoing studies of the structural chemistry of molecules of the general formula RSn(S 2 CNR′R′′) 2 Cl, R, R′, R′′ = alkyl and/or aryl [2], the structure of the R = n-butyl, R′ = n-propyl and R′′ = secbutyl derivative, has been investigated. The structural motif adopted by the title molecule is common to all other molecules having this generic formula [2][3][4][5][6][7][8][9][10][11][12]. Thus, the Sn atom exists within a C, Cl, S4 donor set that describes a distorted octahedral geometry, being coordinated by n-butyl- …”

Structural systematics of RSn(S 2CN R′ R″) 2Cl compounds

“…2, exhibited homogeneity in their molecular structures with octahedral coordination geometries defined by chelating dithiocarbamate ligands and with mutually cis tin-bound organic and chloride substituents [21][22][23][24][25][26][27][28][29][30]. It is noted that all these examples contain symmetrically substituted dithiocarbamates ligands, i.e.…”
