Abstract: | By self‐assembly of a Salamo‐type ligand H2L H2L = 1,2‐bis(3‐methoxysalicylideneaminooxy)ethane] with Ni(OAc)2 · 4H2O, Ce(NO3)3 · 6H2O, and H2bdc (H2bdc = terephthalic acid), a novel NiII‐CeIII heterometallic complex, {Ni(L)Ce(NO3)2(CH3OH)(DMF)}2(bdc)], was obtained. Two crystallographically equivalent Ni(L)Ce(NO3)2(CH3OH)(DMF)] moieties lie in the inversion center, and are linked by one bdc2– ligand leading to a heterotetranuclear dimer, in which the carboxylato group bridges the NiII and CeIII atoms. Moreover, the photophysical properties of the NiII‐CeIII complex were studied. |
