Abstract

The 1H, 13C and 119Sn NMR and far-IR spectra of tris (neophyl) stannanes,(PhCMe2CH2) 3SnX,(Neo) 3SnX,[1: X= F, Cl, Br, I, N3, NCS, OSn (Neo) 3 and OAc], and the crystal structures of 1 (X= Br, I, N3, NCS and OAc) are reported. The compounds 1 (X= Br, I, N3 and NCS) and the previously reported 1 (X= Cl) all contain four-coordinate tin centers, with distorted tetrahedral geometries in the solid state. In contrast, 1 (X= OAc) is five-coordinate ...
