| Popis: | Treatment of monophosphine gold(I) complex [P(CH2CH2CN)3(AuCl)] or bisphosphine gold(I) complex [dpph(AuCl)2, dpph = 1,6-bis(diphenylphosphino)hexane] with sodium 2-amino-5-mercapto-1,3,4-thiadiazolate (NaSSNH2) or sodium 6-amino-2-mercaptobenzothiazolate (NaSSCNH2) affords a series of gold(I) thiolates: [P(CH2CH2CN)3(Au(SSNH2))] 1, [dpph(Au(SSNH2))2] 2, [P(CH2CH2CN)3(Au(SSCNH2))] 3, and [dpph(Au(SSCNH2))2] 4. The crystal structures of 1 and 1·DMF feature a similar ribbon pattern with molecules linked through hydrogen-bonding interactions, and 2·DMF displays a novel pseudo double-helical structure assembled into a two-dimensional sheet via hydrogen bonding. When the SSNH2 ligand is replaced by SSCNH2, the cyano group of the P(CH2CH2CN)3 complex engaging in hydrogen-bonding interactions contributes to the formation of a two-dimensional sheet structure for 3. Complex 4, featuring a dinuclear S-shaped structure, is further associated into a one-dimensional chain via a weak N−H···S interaction. In the present... |
