Dinuclear complexes of the composition Cu 2 I 2 L 2 Py 2 and Cu 2 I 2 L 4 are obtained by the reaction of 10‐(aryl)phenoxarsine ligands (L) with copper iodide in pyridine or non‐coordinated solvent. Unexpectedly the 1D polymeric complex [Cu 2 I 2 L 4 ] n is formed as the only product by the reaction of 10‐(p‐ethoxyphenyl)phenoxarsine with CuI in the molar ratio 1 : 2. All complexes and the initial phenoxarsine ligands are fully characterized by elemental analysis, NMR‐ and IR spectroscopy. X‐ray structure is determined for eight complexes and five ligands. In the 1D coordination polymer [Cu 2 I 2 L 4 ] n copper atoms are in zigzag‐like chain arrangement demonstrating the first example of such Cu‐I−Cu‐I binding. The empirical Tolman cone angles for 10‐(aryl)phenoxarsine ligands in complexes are calculated to lie in the range of 125–152°. The dependence of the Tolman angle values on the position of aryl substituent at arsenic atom is demonstrated.
