Tris(2-methyl-2-phenylpropyl)(4-nitrophenolato)tin(IV)

Abstract

The Sn atom of the monomeric title compound, [Sn(C10H13)3(C6H4NO3)], adopts a distorted SnOC3 tetra­hedral geometry.

Syntheses, structures, and1H,13C{1H} and119Sn{1H} NMR chemical shifts of a family of trimethyltin alkoxide, amide, halide and cyclopentadienyl compounds

“…6e Table 2 shows the 1 H NMR data. However, there is a difference between the Me 3 Sn resonances in dichloromethane-d 2 or chloroform-d 1 and those found in acetonitrile-d 3 or tetrahydrofuran-d 8 , with the latter two having the most upfield resonances. The observed J1 H-119 Sn constant for the Me 3 Sn group of all complexes is measured to be between 49-61 Hz, which is typical of this type of coupling.…”

“…The 1 H NMR chemical shifts are reported at two concentrations (4-10 mM and 0.3-1.0 M) while the 13 C{ 1 H} chemical shifts are only reported at the higher concentration in benzene-d 6 , toluene-d 8 , dichloromethane-d 2 , chloroform-d 1 , acetonitrile-d 3 , and tetrahydrofuran-d 8 . The 1 H NMR chemical shifts are reported at two concentrations (4-10 mM and 0.3-1.0 M) while the 13 C{ 1 H} chemical shifts are only reported at the higher concentration in benzene-d 6 , toluene-d 8 , dichloromethane-d 2 , chloroform-d 1 , acetonitrile-d 3 , and tetrahydrofuran-d 8 .…”

“…The 119 Sn{ 1 H} resonances in benzene for Me 3 SnX (X = halides, NEt 2 , N(SiMe 3 ) 2 and SnMe 3 ) 6d,e,g have been reported before and are shown here for completion. Compound 1 is sparingly soluble in benzene-d 6 , toluene-d 8 , and acetonitriled 3 ; 13 C{ 1 H} NMR data could not be obtained in those solvents. 6e Table 2 shows the 1 H NMR data.…”

“…4 Although their use as marine antifoulants is being phased out, new organotin derivatives with N, O and S donating groups are showing promise as antimicrobial, antifungal, and anticancer agents. For completeness, we have compiled 1 H and 13 C{ 1 H} NMR data of eleven Me 3 SnX compounds in six common deuterated solvents (benzene-d 6 , toluene-d 8 , dichloromethane-d 2 , chloroform-d 1 , acetonitrile-d 3 , and tetrahydrofuran-d 8 ). 6 Herein, we report the synthesis and characterization of a family of trimethyltin amide, alkoxide, and cyclopentadienyl compounds.…”
