Syntheses, structures, fluorescence and thermal properties of three lanthanide coordination polymers built by N-benzoyl-N′-(4-benzoxy)thiourea

Three novel lanthanide 1-D chain coordination polymers, namely {[Tb(μ2-L)2(η2-NO3)(CH3OH)(H2O)]·0.5CH3OH·0.5H2O}n (1), {[Dy(μ2-L)2(η2-NO3)(CH3OH)(H2O)]·H2O}n (2) and {[Ce(μ2-L)2(η2-NO3)(H2O)3]·H2O}n (3) (HL=N-benzoyl-N′-(4-benzoxy)thiourea), have been prepared and characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction. The luminescence properties and themostabilities of polymers 1-3 have been determined as well.
