The synthesis of [La (Phen) 2 (NO3) 2 (H2O) 2] ClO4 · 2Phen · H2 O (1 with the chemical formula of C48H3 8ClN10 O13 La, Mr = 1 1 3 7.2 4, Phen = phenanthroline) The crystal structure of triclinic system belongs to the triclinic system determined by X-ray single crystal diffraction. The P 墿 space group is a = 1 1 .2 5 0 (4), b = 1 3 .3 64 (4), c = 1 6.3 2 7 Α = 103.042 (6), β = 90.327 (6), γ = 99.5 67 (6) °, V = 2 3 5 5 .8 (1 2) 3, Z = 2, Dc = 1.660 3 g · cm -3, F (0 0 0) = 1 1 48, μ = 1 .0 42 mm -1, R = 0 .0 5 69, wR = 0 .1 0 64 . 1 consists of [La (Phen) 2 (NO3) 2 (H2O) 2] + cations, ClO-4 anions, two cocrystalline Phen molecules and one H2O molecule. The central metal La (III) ion in the inner boundary is a ten-coordinated deformed double-capped tetragonal antiprism whose coordination environment is surrounded by six oxygen atoms from two bidentate nitro groups and two H 2 O molecules And four nitrogen atoms from two Phen ligands to form a mononuclear bivalent cation with 1 water molecule, 1 ClO-4 anion and two Phen molecules. The entire molecule forms a 3D network structure through intermolecular hydrogen bonding.
