The unit cell parameters are: a = 1.4693 (2), b = 1.5882 (3) .c = 1.9916 (4) nm, α = 90.92 2), β = 92.93 (1), γ = 103.73 (1) ° ", V = 4.507nm ~ 3, D_c = 1.29g.cm -3, Z = 2. The complexes are binuclear molecules, There are three organic ligand molecules in the molecule. One of the organic ligands links two La (III) atoms with two carbonyl groups. In addition, each La (III) has one organic ligand and three nitrate ligands , The organic ligands coordinate to two carbonyl groups, and all three nitrate are bidentate ligands. The coordination number of both La (Ⅲ) is 9
