Synthesis, Structure and Properties of (n-Bu4N3[Mo6O18NNAr(NO2)2]

Abstract

Abstract: The title compound was synthesized and characterized by means of elemental analysis, IR, DTA-TG and UV. Its single crystal structure was solved by using direct methods. The compound crystallizes in the orthorhombic space group P_mcRwith lattice parameters: a=1. 7261(2), b=l. 7537(3), c=2. 4258(3) nm. V=7. 34220 nm³, F(000)=3648, Z=4. The structure was refined to conventional discrepancy factors of R=0. 060 for 3176 observed reflections [Ⅰ>3σ/(Ⅰ)]. The anion represents a modification of the well-known [Mo₆O₁₉]^2-anion, in which a single terminal oxo group is replaced by a 2,4-dinitrophenyl hydrazine ligand while the structure integrity of the hexanuclear framework is maintained.

Key words: Crystal structure, Distortion, 2,4-dinitrophenylhydrazine
