-Ph2P–C6H4–CO–NH–R)]Cl. The subsequent reaction of these complexes with KPF6 produced the cationic species 2a–d [RuCl(η6-p-cymene)(o-Ph2P–C6H4–CO–NH–R)][PF6] in which phosphino-amides also act as rigid P,O-chelating ligands. The molecular structures of 2b–d were determined crystallographically. Amide deprotonation is achieved when complexes 2a–d were made react with 1 M aqueous solution of KOH, affording
