Syntheses, crystal structures and photoluminescent properties of dinuclear and tetranuclear zinc complexes with 1,4-bis(2,2':6',2″-terpyridine-4'-yl)benzene

Two zinc complexes, [(HCOO)2Zn(μ-bteb)Zn(OOCH)2]·2H2O (1) and {[(HCOO)Zn(μ-bteb)Zn(OOCH)]2(μ-O)2}·DMF·6H2O (DMF = dimethylformamide) (2), containing a π-conjugated “back to back” bis-terpyridine li...
