Abstract

The preparation and physical and spectroscopic properties of eight compounds of the type Me4Sn2X2 (X  O2CR, S2CNR2, S2P(OR)2) are described, starting from Me4Sn2Cl2. The spectroscopic data indicate that X functions as an isobidentate ligand. The tintin coupling constants are extremely large (ca. 11–15 kHz), and can be correlated with the pKa values of the corresponding acids HX.

    Noteworthy is the similar value of the coupling constant through one and two bonds in the cubane, in contrast to propellane. Dinuclear species containing pentacoordinated Sn atoms exhibit 1J(Sn,Sn) from 10 to 15 kHz and cover the opposite end of the SSCC scale (Fig. 11B) [73,79,80]. The first example of the coupling constant 117Sn-119Sn across the SnSn double bond, 1340 Hz, has been measured by the 119Sn CPMAS NMR technique. [81]
