In the water-ethanol mixed system, the complexes of 2-carbonyl propionic acid salicyloyl hydrazone (C10 H10 N2 O4), 1,10-phenanthroline (phenylene) and Dy (NO3) 3 3H2 O [Dy (C10H8N2O4) (phen) (NO3) (H2O) 2] · H2 O. The complex belongs to the monoclinic system with space group P2 1 / c and unit cell parameter a = 1 5 2 4 (3) nm, b = 1 10 18 (19) nm, c = 1 468 (3) nm, β = 92 2 8 (2) °, V = 2 4 63 (7) nm3, Z = 4, μ = -1, Dc = 1 83 1 g / cm3, F (0 0 0) = 13 40, R = 0 0 3 14, wR = 0 0 660, GOF = 0 966. The test results show that the single crystal structure is dysprosium 9 coordination complexes, one of 2 carbonyl propionic acid salicyloyl hydrazone molecules with carboxyl oxygen, amido carbonyl oxygen and CN in the nitrogen and Dy3 + tridentate coordination, the formation of two stable co-side five-membered ring, a 1,10 phenanthroline molecules coordinate in bidentate mode, a nitrate and two water molecules are also involved in coordination at the same time, in the space is twisted single-cap square anti-prism, and there is a free water around the complex Luminescent properties of the complexes show that the complexes have good fluorescence properties
