Treatment of the chloro-bridged dinuclear complex [Pd3,4-(MeO)2C6H2C(H)N(Cy)-C6,N}(μ-Cl)]2 (1) with homobidentate [P,P], [As,As], [N,N], and heterobidentate [P,As], [P,N] ligands in a 1:1 molar ratio gave the dinuclear complexes [Pd[3,4-(MeO)2C6H2C(H)N(Cy)-C6,N](Cl)}2μ-L}] (L = Ph2PC4H6(NH)CH2PPh2 (2); Ph2As(CH2)2AsPh2 (3); 1,3-(NH2CH2)2C6H4 (4); Ph2P(CH2)2AsPh2 (5); Ph2P(CH2)2NH2 (6)), with the
氯桥联双核络合物[Pd 3,4-(MeO)2 C 6 H 2 C(H)N(Cy)-C 6,N }(μ-Cl)] 2(1)的处理为纯正的[ P,P ],[ As,As ],[ N,N ]和异双峰[ P,As ],[ P,N ]配体以1:1的摩尔比得到双核络合物[Pd [3,4- (MeO)2 C 6 H 2 C(H)N(Cy)-C 6,N ](Cl)}2 μ-L}](L = Ph 2 PC 4 H 6(NH)CH 2 PPh 2(2); Ph 2 As(CH 2)2 AsPh 2(3); 1,3-(NH 2 CH 2)2 C 6 H 4(4); Ph 2 P(CH 2)2 AsPh 2(5); Ph 2 P(CH 2)2 NH 2(6)),双齿配体桥接两个环金属化片段。
