Abstract: | The title complex, Ag4(C7H5O3)2(C8H6N2)4(C7H6O3)4], lies about an inversion centre and has a unique tetranuclear structure consisting of four AgI atoms bridged by four N atoms from two 1,8‐naphthyridine (napy) ligands to form an N:N′‐bridge and four O atoms from two salicylate (SA) ligands to form an O:O′‐bridge. The Ag atoms have distorted octahedral coordination geometry. The centrosymmetric Ag4 ring has Ag—Ag separations of 2.772 (2) and 3.127 (2) Å, and Ag—Ag—Ag angles of 107.70 (4) and 72.30 (4)°. All SA hydroxy groups take part in intramolecular O—H?O hydrogen bonding. In the crystal packing, the napy rings are oriented parallel and overlap one another. These π–π interactions, together with weak intermolecular C—H?O contacts, stabilize the crystal structure. |
