1,5‐bis( R )‐3,7‐bis[2‐(pyridine‐2′‐yl)ethyl)‐1,5‐diaza‐3,7‐diphosphacyclooctanes 1 and 2 and their copper(I) complexes 3 and 4 were developed. The butterfly‐shaped copper‐iodide core and unusual P,N‐chelate and P,P‐bridged coordination mode of the heterocyclic ligand in the dinuclear complexes 3 and 4 were revealed. Complexes 3 and 4 display emission in green range of spectra, with lifetimes in a microsecond domain and quantum yields of luminescence in solid‐state up to 38 %. Thermochromic effects found for the phosphorescence of 4 in solutions are ascribed to rigidochromism.
