摘　　要：1,10 Phenanthroline tris(4 methoxybenzoate)europium, Eu( p MOBA) 3phen(where p MOBA= p methoxybenzoate and phen=1,10 phenanthroline) has been obtained in the ethanol solution. The crystal consists of binuclear molecules of the title compound. In the binuclear molecule each Eu 3+ ion is coordinated not only by four oxygen atoms from the bridging carboxylates, but also by two oxygen atoms of a bidentate carboxyl group and two nitrogen atoms of a phen chelating ligand, giving coordination number of eight. Eu O distances range from 0 2336(3) to 0 2483(3) nm. The average Eu N distance is 0 2624(4) nm. Luminescence data indicate that one Eu 3+ ion site is in low symmetry in the complex.1,10 Phenanthroline tris(4 methoxybenzoate)europium, Eu( p MOBA) 3phen(where p MOBA= p methoxybenzoate and phen=1,10 phenanthroline) has been obtained in the ethanol solution.
