摘要
The title compound, [La(BTC)(H2O)6]n 1 (H3BTC = benzene-1,3,5-tricarboxylic acid), has been synthesized by the hydrothermal reaction of La(NO3)3·3H2O with H3BTC and Na2CO3, and its structure was determined by single-crystal X-ray diffraction. The crystal structure is of monoclinic, space group Cc with a = 11.5289(3), b = 18.0383(7), c = 7.3507(3)(A), β = 119.5680(10)o, V = 1329.59(8)(A)3, C9H15LaO12, Mr = 454.12, Z = 4, Dc = 2.269 g/cm3, μ = 3.280 mm-1, Flack parameter = 0.07(4), F(000) = 888, R = 0.0316 and wR = 0.0774 for 1312 observed reflections(I > 2σ(I)). Complex 1 features a one-dimensional (1-D) parallel ribbon-like structure. There are extensive hydrogen-bonding interactions involving coordinated water molecules and free carboxylate oxygen atoms. In addition, π-π interactions via benzoic multicarboxylate ligands are discussed. These non-covalent interactions lead to the formation of a 3-D framework.
