Copper(I) complexes with phenylphosphonous acid diamide

详细

Copper(I) halide complexes with phenylphosphonous diamide ligand (L), C₅₆H₁₀₀Br₄Cu₄N₈P₄ (II) and C₅₆H₁₀₀Cu₄I₄N₈P₄ (III), were synthesized and studied by X-ray diffraction to determine their molecular and crystal structures (CIF files CCDC nos. 1426622 (II), 1426623 (III)). The prepared coordination compounds are cubane-like tetramers like L₄Cu₄X₄. During the reaction, copper(I) is coordinated to the phosphorus atom of ligand L. The stability of the complexes depends considerably on the halogen atom. The iodide complexes are most stable during storage.
