gold(I) with the thiolate ligands derived from 2-thiobarbituric acid, SC(4)H(4)N(2)O(2), by single or double deprotonation. The reaction of the corresponding gold(I) trifluoroacetate complex with SC(4)H(4)N(2)O(2) gave the complexes [Au(SC(4)H(3)N(2)O(2))(PPh(3))], 1, [(AuSC(4)H(3)N(2)O(2))(2)(micro-LL)], with LL = Ph(2)PCH(2)PPh(2), 2a, Ph(2)P(CH(2))(3)PPh(2), 2b, or Ph(2)PCH=CHPPh(2), 2c, or the cyclic
金(I)的膦或二膦配合物与衍生自2-硫代巴比妥酸SC(4)H(4)N(2)O的硫醇盐配体的自组装中已经使用了亲和性和氢键的合作力(2)通过一次或两次去质子化。相应的三氟乙酸金(I)络合物与SC(4)H(4)N(2)O(2)的反应生成了络合物[Au(SC(4)H(3)N(2)O(2) )(PPh(3))],1,[(AuSC(4)H(3)N(2)O(2))(2)(micro-LL)],其中LL = Ph(2)PCH(2 )PPh(2),2a,Ph(2)P(CH(2))(3)PPh(2),2b或Ph(2)PCH = CHPPh(2),2c或环状络合物[Au( 2)(micro-SC(4)H(2)N(2)O(2))(micro-Ph(2)PCH(2)CH(2)PPh(2))],在3 LL = Ph(2)P(CH(2))(6)PPh(2),该反应导致二膦配体的损失,从而得到[Au(6)(SC(4)H(3)N(2)
