Abstract The reaction of diphenyl(2-pyrimidyl)phosphine (L) derived complex [Pt(L)2Cl2] with AgNO3 (1:3 M ratio, respectively) results in assembly of heterobimetallic complex [AgPt(L)2(NO3)3], wherein Pt → Ag dative bond of 2.9088(2) A is formed. This complex features thermochromic photoluminescence that appears as ~40 nm red-shift of an emission maximum upon cooling from 300 to 77 K. The related PdII/AgI complex, [AgPd(L)2(NO3)3], showing Pd → Ag dative bond of 2.9098(5) A, has also been synthesized and structurally attested.

由二苯基(2-嘧啶基)膦支持的异双金属 PtII-AgI 配合物:合成和热致变色光致发光

摘要 二苯基(2-嘧啶基)膦 (L) 衍生的复合物 [Pt(L)2Cl2] 与 AgNO3(分别为 1:3 M 比)的反应导致组装异双金属复合物 [AgPt(L)2(NO3)3 ],其中形成了 2.9088(2) A 的 Pt → Ag 配价键。这种复合物具有热致变色光致发光,当从 300 冷却到 77 K 时,发射最大值出现 ~40 nm 红移。相关的 PdII/AgI 复合物 [AgPd(L)2(NO3)3],显示 Pd → Ag 与2.9098(5) A 的键也已合成并在结构上得到证实。
