✦ Synopsis
The dinuclear cyclopalladated compounds [Pd(µ-Cl)Ln] 2 (2) acetato-thiolato bridged complexes [Pd 2 (µ-OAc)(µ-SRm)Ln 2 ] (4). In addition to their mesogenic behavior, the most [HLn = p-C n H 2n+1 OC 6 H 4 CH=NC 6 H 4 OC n H 2n+1 -p (n = 6, 8, and 10)] react with silver thiolates AgSRm (Rm = C m H 2m+1 , interesting feature of these complexes is the cis disposition of the palladium-imine moieties, that can be inferred from m = 6, 8, 10, and 18) to give dinuclear derivatives with mixed bridges [Pd 2 (µ-Cl)(µ-SRm)Ln 2 ] (3). Treatment of derivatives 2 their 1 H-NMR spectra. The cis structure as well as the disposition of the bridges was confirmed by the X-ray with silver acetate (Pd/AgOAc = 2:1) or treatment of [Pd(µ-OAc)Ln] 2 (1) with thiols HSRm (Pd/thiol = 2:1) affords diffraction study of 3 (n = m = 4).
