Synthesis, and copper(I) and gold(I) complexes of imidazole‐based bisphosphine, [2,6‐(PPh₂C₃H₂N₂)₂C₅H₃N] are described. Reactions of [2,6‐(PPh₂C₃H₂N₂)₂C₅H₃N] with one equivalent of CuX (X = Cl, Br or I) yielded either monomeric [{2,6‐{PPh₂C₃H₂N₂}₂C₅H₃N}{CuI}], dimeric [{PPh₂C₃H₂N₂}₂C₅H₃N}{CuCl}]₂, or one‐dimensional (1D) polymeric [{2,6‐(PPh₂‐C₃H₂N₂)₂C₅H₃N}{Cu₃Br₂}]_nCl complexes. Coordination polymer [{2,6‐(PPh₂C₃H₂N₂)₂C₅H₃N}{Cu₃Br₂}]_nCl is a rare example containing alternately arranged copper atoms having tetrahedral and linear geometries. The repeating unit consists of imidazolyl nitrogen atoms from two ligands bind to a copper atom in a linear fashion, whereas two phosphorus atoms from the same ligand are chelated to a tetrahedral copper atom, thus ligand displaying tetradentate behavior. Treatment of bisphosphine with two equivalents of [AuCl(SMe₂)] yielded digold complex [2,6‐(PPh₂C₃H₂N₂)₂C₅H₃N{AuCl}₂]. The structures of most of these compounds were confirmed by single‐crystal X‐ray analyses. These complexes show good photoluminescence properties as well.

Cu（I）和Au（I）络合物中2,6-双（2-（二苯基膦基）-1H-咪唑-1-基）吡啶的多功能配位模式

描述了咪唑基双膦[2,6-（PPh ₂ C ₃ H ₂ N ₂）₂ C ₅ H ₃ N]的合成以及铜（I）和金（I）配合物。[2,6-（PPh ₂ C ₃ H ₂ N ₂）₂ C ₅ H ₃ N]与一当量的CuX（X = Cl，Br或I）的反应生成单体[{2,6- {PPh ₂ C ₃ H ₂ N ₂ } ₂ C ₅ H ₃ N} {CuI}]，二聚体[{PPh ₂C ₃ H ₂ N ₂ } ₂ C ₅ H ₃ N} {CuCl}] ₂，或一维​​（1D）聚合物[{2,6-（PPh ₂ -C ₃ H ₂ N ₂）₂ C ₅ H ₃ N} {Cu ₃ Br ₂ }] _n Cl配合物。配位聚合物[{2,6-（PPh ₂ C ₃ H ₂ N ₂）₂ C ₅ H ₃ N} {Cu ₃ Br ₂ }]_n Cl是包含具有四面体和线性几何形状的交替排列的铜原子的罕见实例。重复单元由来自两个配体的咪唑基氮原子以线性方式结合至铜原子，而来自相同配体的两个磷原子被螯合至四面体铜原子，因此配体表现出四齿行为。用两当量的[AuCl（SMe ₂）]处理双膦，可得到二甲双胍络合物[2,6-（PPh ₂ C ₃ H ₂ N ₂）₂ C ₅ H ₃ N {AuCl} ₂]。这些化合物大多数的结构已通过单晶X射线分析确认。这些配合物也显示出良好的光致发光性质。
