Abstract
A mixed ligand lanthanum complex H-bonded with a crown ether benzo-15-crown-5 (B15C5), [La(NO3)3(H2O)2phen]B15C5 (phen = phenanthroline), was synthesized and characterized by elemental analysis, infrared spectrum, and X-ray crystal structure analysis. The crystals of the title compound are monoclinic, P21, with a = 18.879(6) Å, b = 20.110(5) Å, c = 19.358(4) Å, V = 6623.4 Å3, β = 115.68(3)°, Z = 8, D calc = 1.623 g/cm3. In this complex, two nitrogen atoms from phen and eight oxygen atoms, six from NO3 − and two from H2O, coordinate to La(III), forming a 10-coordination structural unit. The two H2O molecules are located in opposite directions of the unit, each H2O is H-bonded with two O atoms of the B15C5, and each B15C5 molecule is H-bonded with two H2O molecules on opposite sides, thus an infinite supramolecular chain forms. The title compound has a layered structure, and in each unit cell there exists one 3D channel.
