title: Ferromagnetic exchange in two dicopper(II) complexes using a mu-alkoxo-mu-7-azaindolate bridge.
abstract: Syntheses, structures, and magnetic properties of two heterobridged mu-alkoxo-mu-7-azaindolate dicopper(II) complexes, [Cu(II)2(L-F)(mu-C7H5N2)] (1) and [Cu(II)2(L-H)(mu-C7H5N2)].CH3OH (2) (H3L-F = 1,3-bis(3-fluorosalicylideneamino)-2-propanol; H3L-H = 1,3-bis(salicylideneamino)-2-propanol) have been reported. Aside from being a new type of heterobridged complex, 1 and 2 exhibit ferromagnetic interaction (2J = 52 cm(-1) for 1 and 33.4 cm(-1) for 2) despite orbital complementarity (7-azaindolate HOMO is antisymmetric).
