Abstract
The synthesis and characterization of a family of novel alkaline earth meta l stannides, in addition to tri- and pentastannanes are described. [Ba(18-c rown-6)(HMPA)(2)][SnPh3](2) (4), [Ca(18-crown-6)(HMPA)(2)][Sn(SnPh3)(3)](2) (5), and [Sr(18-crown-6)(HMPA)(2)][Sn(SnPh3)(3)](2) (6) were synthesized b y insertion of the corresponding alkaline earth metals into the tin-tin bon d of hexaphenyldistannane. Ph3SnSnPh2SnPh3 (7), and Sn(SnPh3)(4) (8) became available by treating 4 with diphenyldichlorostannane, Ail compounds were studied by NMR spectroscopy, and X-ray crystallography. The stannanes 7 and 8 were also characterized by elemental analysis. (C) 2000 Elsevier Science B.V. All rights reserved.
