Abstract
The reaction of (i-Pr)2P(S)N(SiMe3)2 (1) with SnCl4 in 2:1 ratio yield s under elimination of ClSiMe3 the four-membered spirocycle [(i-Pr)2P( S)NSiMe3]2SnCl2 (2). The molecular structure of 2 was investigated by an X-ray structure analysis. Compound 2 crystallises in the monoclinic space group P2(1), Z = 2, a = 938.1(1), b = 1 424.1(2), c = 1 207.2(1 ) pm, beta = 110.59(1)degrees, R = 2.05% for 4102 reflexions. Compound 2 is a spirocycle with two Sn-N-P-S-rings joined at tin. The two ring s are in cis-position.
