“…Up to now, the solid-state structures of subclass i have been described for Hal = Cl and R = Et (Lecomte et al, 1976), R = i Pr, i Bu (Puff & Reuter, 1989), R = n Bu (Holmes et al, 1988) and R = (6,6-dimethylbicyclo[3.1.1]hept-2-yl)methyl (Beckmann et al, 2009), but for subclass ii, only the crystal structure of the isobutyl compound with Hal = Cl and LB = DMF (Reuter & Ye, 2013) is known. In the case of subclass iii, only the single-crystal structure determination of the methyl compound with Hal = Cl and n = 3 (Johnson & Knobler, 1994) exists and for subclass iv, the n-butyl compounds with Hal = Cl, BB = methylbenzothiazole and n = 4 (Wei, 1994), and BB = dimethyl cyanocarbonodithioimidate and n = 4 (Mbaye et al, 2023) or n = 2 (Diop et al, 2022) are available.…”

Di-μ-hydroxido-bis[dibromido(dimethylformamide-κO)ethyltin(IV)], [Sn2Br4(C2H5)2(OH)2(C3H7NO)2], was prepared from ethyltin(IV) bromide and N,N-dimethylformamide (DMF) in air. The crystal structure exhibits the typical structural features of dimeric Lewis-base-stabilized monoorganotin(IV)–dihalide–hydroxides, RSnHal2(OH), i.e. two octahedrally coordinated Sn atoms are linked together via two bridging hydroxide groups, resulting in a centrosymmetric four-membered rhomboid-like Sn–OH ring with acute angles at the Sn atom, obtuse angles at the O atoms and two different tin–oxygen bond lengths. With the shorter bond trans to the ethyl group, this observation underlines once more the so-called trans-strengthening effect in monoorganotin(IV) compounds with octahedrally coordinated Sn atoms. Differences and similarities in the bond lengths and angles in the four-membered Sn–OH rings have been worked out for the rings in dimeric diorganotin(IV)–halide–hydroxides, [R 2SnHal(OH)]2, and hydrates of dimeric tin(IV)–trihalide–hydroxide–aqua–hydrates, [SnHal3(OH)(H2O)]2·nH2O.

The controlled base hydrolysis of 2,6-Mes(2)C(6)H(3)SnCl(3) (1; Mes=mesityl) provided 2,6-Mes(2)C(6)H(3)Sn(OH)Cl(2).H(2)O (2) and the trinuclear organostannonic acid trans-[2,6-Mes(2)C(6)H(3)Sn(O)OH](3) (3), respectively. In moist C(6)D(6), 3 reversibly reacts with water to give the monomeric organostannonic acid 2,6-Mes(2)C(6)H(3)Sn(OH)(3) (3 a). The reaction of 3 with (tBu(2)SnO)(3), Ph(2)PO(2)H, and NaH, gives rise to the multinuclear hypercoordinated organostannoxane clusters [tBu(2)Sn(OH)OSnR(OH)(2)OC(OSntBu(2)OH)(2)(O)SnR(OH)(H(2)O)](2) (5), [RSn(OH)(2)(O(2)PPh(2))](2) (6), and Na(3)(RSn)(4)O(6)(OH)(3) (7), respectively (R=2,6-Mes(2)C(6)H(3)). The characterization of the new compounds is achieved by multinuclear NMR spectroscopy and electrospray mass spectrometry in solution and (119)Sn MAS NMR spectroscopy, IR spectroscopy, and X-ray crystallography in the solid-state.
