Tetranuclear Complexes Based on a Dynamic Metal−Metal Linkage, [(μ4-X)Rh4(CO)4(PNNP)2]n+ (X/n = RC⋮C/1 (Acetylide), C2/0 (Dicarbide))
摘要:
Tetrarhodium complexes with a PNNP auxiliary, [(mu(4)-X)Rh-4(CO)(4)(PNNP)(2)](n+) (X/n = RCequivalent toC/1 (acetylide), C-2/0 (dicarbide); PNNP = 3,5-bis((diphenylphosphino)methyl)pyrazolato), are integrated mainly through M-X interactions and exhibit unique dynamic behavior associated with reversible metal-metal bond cleavage and recombination processes.
