The Isoelectronic Replacement of E = P⁺ and Si in the Trinuclear Organotin−Oxo Clusters [Ph₂E(OSntBu₂)₂O·tBu₂Sn(OH)₂]

Abstract

The trinuclear organotin−oxo cluster [ (5) where E = Si, C, B and X = OH, F. Compound 6 was characterized by multinuclear NMR spectroscopy, IR spectroscopy, electrospray mass spectro-

Ylenes in the MII→SiIV (M=Si, Ge, Sn) Coordination Mode

“…The NC at the Sn site in 1 is notably less positive than, for example, the NC reported by Jurkschat et al for pentacoordinate Sn IV compounds (ca. + 2.5), [23] and the one reported for Sn IV in a structurally related Pd II !Sn IV system (+ 2.31). [24] Instead, it is close to the NC of + 1.48 reported by Schoeller et al for a bis(amidinate)Sn II complex.…”

“…Yield: 0.80 g (1.04 mmol, 51 % taking into consideration that two molecules of Cl 3 SiSiCl 3 are required for the formation of one molecule of 3 a, acoompanied by the formation of Me 3 SiCl, Cl 2 Si(mt) 2 , ClSi(mt) 3 ).

Reactivity of ditert-butyldimethoxystannane with carbon dioxide and methanol: X-ray structure of the resulting complex

“…The closer chemically related structures that have been published correspond to the compounds [R 2 Si(OSntertBu 2 ) 2 O(tert-Bu 2 Sn)(OH) 2 ] (R = CH 3 , Ph) [16,28] [29]. Notable in the structure is the presence of intermolecular hydrogen bonding between the hydroxy protons and one oxygen atom of the O 3 SCF 3 groups, giving rise to the formation of an infinite chain in the crystal lattice.…”

Stannylen oder Metallastanna(IV)‐ocan – eine Sache des Formalismus

“…B. + 2.5 für pentakoordinierte Sn-Zentren in SnOxo-Clustern, [15] während für Stannylen 4 diese NL zu + 1.44 berechnet wurde. Ebenso wurden für Sn II -Bis(amidinate) ({Sn II N 4 }-Gerüst) NLs < + 1.5 erhalten.…”
