Synthesis and Crystal Structures of Two New Lanthanide Coordination Polymers with 2,3-Dichlorobenzoic Acid and 4,4-Bipyridine

Two new lanthanide complexes [Ln(2,3-DClBA)(3)(CH3CH2O)(H2O)](2n) <bold> n</bold>(4,4-bipy) (Ln = Eu (1),Tb (2); 2,3-DClBA = 2,3-dichlorobenzate; 4,4-bipy = 4,4-bipyridine) have been synthesized by aqueous solution synthesis and characterized by elemental analysis and X-ray crystallography analysis. The results showed that complexes 1 and 2 are isostructural and are built of two-dimensional layered structures. Complex 1 belongs to triclinic system, space group P1, a = 9.7239(7) , b = 12.0736(13) , c = 14.6611(12) , = 103.356(2)degrees, = 93.0140(10)degrees, = 97.6200(10)degrees, V = 1653.7(3) (3), Z =1, = 1.735 g/cm(3), = 18.453 mm(-1), F(000) = 850, the final R = 0.0591 and wR = 0.0963 for all data. Complex 2 belongs to triclinic system, space group P1, a = 9.6990(7) , b = 12.0380(11) , c = 14.6060(12) , = 103.274(2)degrees, = 93.0930(10)degrees, = 97.4250(10)degrees, V = 1639.7(2) (3), Z = 1, = 1.764 g/cm(3), = 2.694 mm(-1), F(000) = 854, the final R = 0.0545 and wR = 0.0911 for all data.
