International Journal of Novel Research in Physics Chemistry & Mathematics, ISSN 2394-9651, Novelty Journals, Website: www.noveltyjournals.com<br/>Abstract: The use of N'–(1–(pyridin–2–yl)ethylidene)nicotinohydrazide (HL) in Yttrium (III) chemistry has yielded dinuclear complex. The 1:1 Y(CH3COO)3.6H2O/HL in methanol afforded the complex {[Y(L)(h2–OOCCH3)(H2O)](h1:h2:µ–OOCCH3)2[Y(L)(h2–OOCCH3)(H2O)]}. The structure of the complex were solved by single crystal X–ray crystallography. In the complex the Y3+ 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 Y3+ 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) Å3, Z = 8, R1 = 0.0345, wR2 = 0.0797. The supramolecular structures are consolidated by multiple hydrogen bonds. Keywords: Schiff base, dinuclear complex, Yttrium, tricapped prism.
