In the water-ethanol mixed system, the reaction of 2-oxopropionate salicyloyl hydrazone (C10H10N2O4) and 1,10-phenanthroline (Phen) with Nd (NO3) The crystal belongs to the triclinic system with a space group of P-1. The unit cell parameters are a = 1.390 1 (2) nm, b = 1.407 3 (d (C10H8N2O4) Α = 74.298 (2), ° β = 68.911 (2), ° γ = 71.703 (2), ° V = 3.009 1 (8) nm3, Z = 2, μ = 1.800 mm-1, Dc = 1.690 g / cm3, F (100) = 1 544, R = 0.028 4, wR = 0.063 0, GOF = 1.010. N d (Ⅲ) 9 coordination unit, each N d (Ⅲ) with two 2- carbonyl propionic acid salicyyl hydrazone and three water molecules coordination; each 2- carbonyl propionic acid salicyyl hydrazone carboxyl Oxygen, carbonyl oxygen in amido and nitrogen in C = N coordinate with N d3 + to form two co-adjacent stable five-membered rings. The other three coordination atoms come from oxygen atoms in three water molecules respectively, The structural unit is a twisted, single-capped tetragonal antiprism with one free 1,10-phenanthroline molecule and four water molecules around each of the nine Nd coordination units. The entire complex is connected by hydrogen bonding Into a three .IR supramolecular mesh and thermal analysis corroborated the composition of the complexes.
