摘要：

Single-crystal X-ray diffraction analysis of [2,6-(Me2NCH2)(2)C6H3](2)SnF2 reveals that only one of the two dimethylaminomethyl groups of each pincer-type ligands [2,6-(CH2NMe2)(2)C6H3](-) is coordinated to the tin atom at Sn-N distances of 2.576(2) and 2.470(2)angstrom, inducing chirality of the latter. The tin atom exhibits a distorted octahedral trans(C,C)cis(N,N)cis(F,F) configuration. Extensive intra- and intermolecular C-H center dot center dot center dot F hydrogen bonding is observed with the latter giving rise to formation of polymeric chains.
