Abstract

Synthesis and characterization of three aluminum-containing tin(IV) heterobimetallic sulfides are reported. The reaction of [LAI(SLi)2(THF)2]2 [L = HC(CMeNAr)2 Ar = 2,6-[Pr2C6H3] with Ph2SnCl2, MeSnCI4 in THF respectively affords LAI(mu-S)2SnPh2, LAI(mu-S)2SnMe2, and LAI(mu-S)2Sn(mu-S)2AIL in moderate yields.

Abstract

Sn((super n)Bu)(Cl){(OCH2CH2S)(sub 2)Sn((super n)Bu)}(sub 2) was isolated from the reaction of (super n)BuSnCl(sub 3) and Na(sub 2)(SCH(sub 2)CH(sub 2)O). The X-ray structure shows that Sn((super n)Bu)(Cl){(OCH2CH2S)(sub 2)Sn((super n)Bu)}(sub 2) is a trimetallic tin(IV) compound connected via oxygen atom bridges.

Abstract

The synthesis and characterization of novel M[(OPPh2)(sub 2)N](sub 2).nTHF (M = Sr (2), Ba (3)) complexes, along with the crystal structures of the dinuclear species Sr2[OPPh2)(sub 2)N](sub 4).2C3H6O3 and Ba2[(OPPh2)(sub 2)N](sub 4).2C4H8O3 are described. These compounds contained coordinated carboxylic acids obtained from the oxidative degradation of DME and THF, respectively, which were used as solvents for crystallization.

Abstract

Two heterobimetallic alumophosphite derivatives were synthesized by using an unusual alumophosphite reagent. The lithium salts showed a unique coordination mode of phosphite unit in one and a carbon-free heterocycle in the other.
