A strategy for controlling charge and conformation in 2,2′-bipyridine complexes for use in photonic applications
摘要:
The complex [(Bu4N)-Bu-n][Cu(H1)(2)]center dot H2O (H(2)1 = 3,3'-dihydroxy-6,6'-dimethyl-2,2'-bipyridine) is readily formed from the reaction of H(2)1 with [Cu(MeCN)(4)][PF6] in the presence of [(Bu4N)-Bu-n]Br; in the solid state the anion comprises a discrete dinuclear {[Cu(H1)(2)](H2O)(2)[Cu(H1)(2)]}(2-) unit in which two oxygen atoms of each [H1](-) ligand and two water oxygens form a chair shaped hydrogen-bonded six-membered ring.
