Adventures in Tin(II) phosphinidene chemistry; insights into the mechanism of P–P and Sn–Sn bond formation

Hydrolysis of bis(dimethylamido)tin to tin (II) oxyhydroxide and its selective transformation into tin (II) or tin (IV) oxide

“…Upon heating, the tin oxychloride Sn 3 O 2 Cl 2 undergoes decomposition/disproportionation to a mixture of Sn 2 O 3 , SnO 2 along with metallic β−Sn [22,26]. Bis(dimethylamido)tin [Sn(NMe 2 ) 2 ], the starting material for the synthesis of Sn 6 O 4 (OH) 4 has previously been used in the synthesis of Sn/SnO x nanoparticles [28], Sn(II)-phosphinidene, -phosphanediide and -imido cage complexes [29][30][31][32] 4 avoids the fine tuning of the reaction conditions during the synthesis as opposed to the reported halide-based synthesis routes.…”

From Coordinated Oxophosphinidene to O,O,P-Bound Arylhypophosphite(2−) To Build a Singular Mo2Sn2O4P2 Metallocycle

“…Both crystals display essentially the same tricyclic metallocycle resulting from the dimerization of two Cp(CO) 2 Mo(PR*O 2 )SnPh moieties (with almost flat PMoSnO rings) so that the terminal O atom of the hypophosphite(2−) ligand in one fragment binds to the unsaturated Sn atom of the second fragment and vice versa, thus creating an inversion center (Figure ). Such a heterometallocyclic arrangement is extremely rare and can be compared to that in the tin(II) phosphinidene anions [{Sn(μ-PR)} 2 (μ-PR)] 2 4− . Besides, the solvent molecules are involved in significant interactions modifying both the overall crystal structure and also the coordination environment of the Sn atom.…”

Crystal Structure of an Unusual Tin Cage Compound, [{Sn(PCy2)3}{(SnCl)3O}] (Cy = cyclohexyl)

“…The chemistry of tin(II) phosphide cage compounds has undergone rapid development in recent years as such compounds have potential applications as, for example, materials precursors. 1 Access to a greater array of such cages containing non-carbon elements other than tin or phosphorus would of interest to materials chemists. In this paper we describe the synthesis and crystal structure determination of such a cage, viz.…”
