Tópico(s)Synthesis and characterization of novel inorganic/organometallic compounds
Resumo[CNCR 2 ] ⊕ , a cation unknown in the free state , is present as terminal ligand bound to a metal in the salts 1 , MCr, W, RPh. On exposure to low‐energy radiation (λ>300 nm) the complexes 1 fragment with cleavage of CR 2 ; with exclusively short‐wave radiation, however, they are stable. The complexes 1 thus belong to the few compounds in which fluorescence from higher ecited states is observed. equation image
