T. Chivers et G. Schatte, Synthesis and characterization of [(BuNSn)-N-t(mu-NBut)(2)TeNBut](mu(3)-SnTe), a stannanetellurone with four-coordinate tin, CHEM COMMUN, (21), 2001, pp. 2264-2265
Treatment of [Li2Te(NBut)(3)](2) with Sn(O3SCF3)(2) or SnCl2 in diethyl eth
er generates the stannanetellurone [(BuNSn)-N-t(mu -NBut)(2)TeNBut] (mu (3)
-SnTe) involving four-coordinate tin with d(Sn=Te) = 2.589(1) Angstrom; the
two Sn and two Te atoms are in different oxidation states (+II/+IV and +IV
/-II, respectively).
