Versatile bridging ability of secondary thioamide group for constructing metal cluster based on pincer complex

The crystallization of the SCS pincer platinum complex with secondary thioamide groups, [4-methyl-2,6-bis(anilinothiocarbonyl)-κ2S,S’-phenyl-κC1]chloroplatinum(II), spontaneously forms a trinuclear cluster complex accompanied by liberating HCl in DMSO/EtOH mixture. The crystal structure of the SNS pincer copper complex with secondary thioamide groups, [2,5-bis(benzylaminothiocarbonyl)-κ2S,S’-pyrrolyl-κN1]chlorocopper(II), exhibits a dimer structure bearing the bridging thioamide group. The thioamide group acts as the bridging ligand of the multimetallic complexes in different anionic and neutral manners.
