Gold Complexes with Selenium Ligands, IV. Preparation, Crystal Structures and Reactions of Phosphine(selenourea)gold(I) Complexes

(Triphenylphosphine)(selenourea)gold(I) chloride +Cl- (1) and the corresponding dppm derivative dppm22+ 2Cl- (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) (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 +SbF6- (4) in good yield.X-ray structrue 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.Key Words: Gold complexes / Selenium ligands / Hydrogen bonding
