  摘要：

  N-甲基化的双（酰胺基吡啶）配体LL = C6H4（1,3-CONMe-4-C5H4N）2与银盐AgNO3，AgO2CCF3，AgO3SCF3，AgBF4和AgPF6的反应得到相应的阳离子去污剂（I）大环[Ag2（micro-LL）2] X2，2a-e。大环中的跨环银...银距离在2.99至7.03 A之间有很大差异，这些差异是由于阴离子结合的不同模式的结合以及存在或不存在银...银二次键合而引起的。在所有配合物中，配体均采用一种构象，其中MeNCO单元的甲基和氧原子相互顺式，但整个大环可以存在于船形（仅X = PF6）或椅子构象中。在配合物2b，c中发现了较短的跨环银...银距离，其中阴离子CF3CO2-和CF3SO3-结合在大环上方和下方，但是在2a，d，e中发现了更长的银...银距离，其中阴离子至少部分存在于分散大环内。溶液中容易发生阴离子交换，并且使用ESI-MS进行的研究表明，阴

• Palladium(II) macrocycles and lanterns

  The coordination chemistry of palladium(II) with the bis(amidopyridine) ligands [LL = Ar(CONMe-4-C5H4N)(2), with Ar = 1,3-C6H4 (1), 5-t-Bu-1,3-C6H3 (2) and 2,5-C4H2S (3) has been investigated. The reaction of [PdCl2(NCPh)(2)] with the ligands in a 1:1 ratio gave the corresponding neutral binuclear macrocyclic complexes trans,trans-[Pd2Cl4(mu-LL)(2)] in all cases. The cavity size and shape in these complexes is highly dependent on the ligand conformation and can change to accommodate guest molecules. The reaction of [PdCl2(NCPh)(2)] with the ligands in a 1:2 ratio gave the mononuclear bis(chelate) derivative [Pd(LL)(2)](2+), with LL = 3, but the binuclear "lantern" or "paddlewheel" complexes [Pd-2(mu-LL)(4)(mu-Cl)](3+), with LL=1 or 2. The selective encapsulation of a chloride ion in these complexes is favored by multiple secondary bonding interactions of the types Cl center dot center dot center dot Pd and Cl center dot center dot center dot HC.

  Reaction of [PdCl2(PhCN)(2)] with the ligand LL = 1,3-C6H4(CONMe-4-C5H4N)(2) gave the neutral dipalladium(II) macrocycle, trans,trans-[Pd2Cl4(mu-LL)(2)], with a short separation between the palladium atoms [Pd(1)Pd-...(2) = 3.63 Angstrom] or the lantern complex [Pd-2(mu-LL)(4)](4+), which acts as a host for chloride ion inclusion in forming the complex [Pd-2(mu-Cl)(mu-LL)(4)](3+), which has a much larger separation between the palladium atoms [(PdPd)-Pd-... = 6.56 Angstrom].
