The 1:1 Y(CH3COO)3.6H2O/HL in methanol afforded the complex {[Y(L)( 2-OOCCH3)(H2O)]( 1 : 2 :µ-OOCCH3)2[Y(L)( 2-OOCCH3)(H2O)]}. The structure of the complex were solved by single crystal X-ray crystallography. In the complex the Y 3+ atoms are doubly bridged by two acetates anions and each metal ion is coordinated by one tridentate monodeprotonated molecule ligand, one bidentate acetate group and one coordinated water molecule. Each Y 3+ atom is nine-coordinated with an environment best described as a tricapped prismatic geometry. Complex crystallizes in the monoclinic space group P21/n with the following parameters : a = 11.3775(11) Å, b = 14.2462(16) Å, c = 12.0082(12) Å, ꞵ = 100.728(10)°, V = 1912.3(3) Å 3 , Z = 8, R1 = 0.0345, wR2 = 0.0797. The supramolecular structures are consolidated by multiple hydrogen bonds.
