    Notes: (Triphenylphosphine)phenylselenolatogold(I), Ph3PAuSePh (1), and the corresponding dppm derivative, [(dppm)(AuSePh)2] (3), are prepared from Me3SiSePh and the appropriate (phosphine)chlorogold(I) complex. The reaction between Ph3PAuCl, Ph2Se2 and AgSbF6 leads to the salt [(Ph3PAu)2SePh]+SbF-6 (2), with a bridging PhSe ligand. X-ray structure analyses of 1 and 2 confirm the expected linear geometry at gold and reveal short Au-Au contacts; both compounds may thus be regarded as loose dimers.

    Gold Complexes with Selenium Ligands, IV(1) Preparation, Crystal Structures and Reactions of Phosphine(selenourea)gold(I) Complexes (1991)
    Weinheim : Wiley-Blackwell

    Notes: (Triphenylphosphine)(selenourea)gold(I) chloride [Ph3PAuSeC- (NH2)2]+ Cl- (1) and the corresponding dppm derivative dppm[AuSeC(NH2)2]22+ 2l- (2) are prepared from SeC- (NH2)2 and the appropriate chloro(phosphine)gold(I) complex. The reaction between 1 and aqueous Na2CO3 leads to the neutral complex μ-selenido{bis[(triphenylphosphine)gold(I)]} (Ph3PAu)2Se (3). An analogous reaction with 2 leads to a dark red oil, which has not yet been characterized. The reaction between 3, Ph3PAuCl, and AgSbF6 leads to the ionic complex [(Ph3PAu)3Se]+SbF6- (4) in good yield. X-ray structure analyses of 1,2, and 3 confirm the expected linear geometry at the gold atom and reveal short intramolecular Au - Au contacts for 2 and 3. Short nonbonding distances between the nitrogen atoms of the amino groups and the chloride ions in the crystal structures of 1 and 2 probably indicate hydrogen bonds.
