Tuning peripheral π-stacking motifs in {Cr(tpy)2}3+ domains (tpy = 2,2':6',2''-terpyridine)

摘要

The homoleptic complexes [Cr(1)2][PF6]3 and [Co(1)2][PF6]3 (1 = 4'-(naphth-2-yl)-2,2':6',2''-terpyridine) have been prepared and structurally characterized. The packing interactions in both complexes are identical, consisting of a combination of naphthyl...naphthyl π-stacking interactions and double naphthyl...pyridine embraces generating chains of cations with alternating long and short M...M contacts.
