Abstract

This work presents the synthesis of the tetracationic paddlewheel complex of 1,8-naphthyridine and palladium(II), [Pd2(µ-napy)4]X4, (X = BF4− or PF6−). Single-crystal X-ray diffraction confirms a D4h symmetric paddlewheel structure encompassing the two Pd units in the metal core coordinated by four ditopic 1,8-naphthyridine ligands, featuring a relatively short Pd–Pd distance. Spectroscopic analyses combined with density-functional theory (DFT) provide insights into the nature of the Pd–Pd and Pd–Napy interactions as well as observed optical absorption frequencies.
