A new phosphine imine 3, [P(Npy)(NHpy)(3)] (py = 2-pyridyl), was synthesized from the phosphonium salt 1, [P(NHpy)(4)]Cl. Subsequent reaction of 1 or 3 with AgClO(4) lead to an unprecedented penta-nuclear Ag(I) complex 4 stabilized by two P(Npy)(2)(NHpy)(2) anions L. The packing diagram of 4 shows an interesting channel structure which contains solvated molecules of methanol and toluene. The diimine ligand L, which represents the N-analogue of a phosphinate ion (H(2)PO(4)(-)), was obtained in situ under the mild reaction conditions in the absence of a base.
一种新的膦亚胺 3，[P(Npy)(NHpy)(3)]（py=2-吡啶基），是由磷盐 1，[P(NHpy)(4)]Cl 合成的。随后，1 或 3 与 AgClO(4)反应生成了一种前所未有的五核银（I）配合物 4，由两个[P(Npy)(2)(NHpy)(2)]（-）阴离子稳定。4 的堆积图显示了一种有趣的通道结构，其中包含甲醇和甲苯的溶剂化分子。二亚胺配体[L]（-），它代表亚膦酸根离子（H(2)PO(4)(-)）的 N 类似物，是在温和的反应条件下，在没有碱的情况下原位得到的。
