Abstract

Benzil bis(3,4,5-trimethoxybenzohydrazone) (I) and 3,3′-dimethoxybenzil bis(benzohydrazone) (II) were synthesized by condensation, acid catalyzed, of the proper α-diketone and the corresponding hydrazide. Compound I crystallizes in the monoclinic system, space group P21/n, with a = 11.464(2), b = 21.098(4), c = 13.837(2) Å, β = 109.50(1)° V = 3154.8(9) Å3 and Dc = 1.319 g/cm3 for Z = 4. Compound II crystallizes in the triclinic system, space group P\(\overline 1\) , with a = 11.106(3), b = 11.728(10), c = 10.656(5) Å, α = 91.86(2), β = 92.68(3), γ = 110.00(2)° V = 1301.1(7) Å3 and Dc = 1.293 g/cm3 for Z = 2.
