Preparation, Structures, and Thermal Decomposition Reactions of Complexes Consisting of TlI, PbII, and SeII and 2,2-Dicyanoethylene-1,1-diselenolate

The 2,2-dicyanoethylene-1,1-diselenolate-containing compounds (AsPh4)2, (AsPh4)2, and (NBu4)2 have been prepared and characterized by single-crystal structure analysis.The molecular structures of the complex anions 1-3 are significantly influenced by the presence of stereochemically active lone pairs. 1 is dimeric with an Se4Tl2 octahedral centre with a Tl-Tl distance of 3.547(4) Angstroem and an average Tl-Se bond length of 3.143(4) Angstroem.In 2 Pb constitutes the centre of a distorted pseudo-trigonal bipyramid PbSe4E ave = 2.948(3) Angstroem> with one equatorial position obviously occupied by the lone-pair E.In 3 the ligands are coordinated to the central Se, which is situated in a centre of symmetry, in an undistorted way giving rise to a ψ-octahedral SeSe4E2 geometry ave = 2.617(2) Angstroem>.The compounds (AsPh4)2 * 1, (AsPh4)2 * 2 and (NBu4)2 * 3 have been decomposed thermally to yield TlSe, PbSe as well as Se.The observed contamination of TlSe and PbSe with As is avoided by using (NBu4)2 * 1 and (NBu4)2 * 2 as precursor materials.
