A nitrogen‐arsenic‐nitrogen (NAN) ligand, phenyldiquinolinylarsine ( pdqa ), was newly synthesized by utilizing diiodophenylarsine as a key precursor. The copper(I) halide (CuX, X = Cl, Br, I) and gold(I) chloride (AuCl) complexes of pdqa were synthesized and their structures were analyzed by NMR spectroscopy and X‐ray crystallography. [CuX( pdqa )] formed pincer complexes, while only the arsenic atom coordinated to the Au I ion in [AuCl( pdqa )]. Moreover, it was found that steric strain for forming the pincer coordination was relieved around the arsenic atom, which had less directional coordination, when comparing the structure of a CuI complex with bidentate ligand diphenylquinolinylarsine.
