The reaction of (R)-1-(1-phenyl)ethyl-3-(O,O-diethylthiophosphoryl)thiourea with Cu(II) acetate is accompanied by copper reduction and leads to the formation of a chiral polynuclear Cu₆L₆ complex. In the crystalline phase the complex consists of six Cu(I) ions alternating with sulfur atoms in the central core, with all six ligands exhibiting similar 1,5-S,S-coordination modes. This structural multinuclear arrangement is preserved in solutions, while at the same time partial disproportionation is observed with the formation of complexes of lower dimensionality. Synchronous redox processes are observed for all six copper ions in the complex in the solid state. The mechanism of copper reduction with the ligand itself as a reducing agent is proposed.

（R）-1-（1-苯基）乙基-3-（O，O-二乙基硫代磷酰基）硫脲的第一个手性多核铜（I）配合物的合成及其在固体和溶液中的表征

（R）-1-（1-苯基）乙基-3-（O，O-二乙基硫代磷酰基）硫脲与乙酸铜（II）的反应伴随铜的还原并导致形成手性多核Cu ₆ L ₆复杂。在结晶相中，络合物由六个Cu（I）离子与中心核中的硫原子交替组成，所有六个配体均表现出相似的1,5- S，S协调模式。这种结构的多核排列保留在溶液中，同时观察到部分歧化并形成了较低维的复合物。对于固态的配合物中的所有六个铜离子，观察到同步氧化还原过程。提出了以配体本身为还原剂的铜还原机理。
