Nassimbeni, L.R., Du Plessis, M.P. and Giles, R.G.F. (1981) Resonance effects in substituted benzoquinones: crystal and molecular structure of 2,5-bisazetidino-1,4-benzoquinone monohydrate and 2,5-bishexamethylenimino-1,4-benzoquinone. South African Journal of Chemistry, 34 (1). pp. 23-27.

Abstract

Crystal data for the title quinones are: Ο,^Η,,Ν,Ο,-Ηρ (4), monoclinic, with a = 5,017(3), b = 9,793(5), c = 12,789(6) A, β = 95,76(2)°, Z= 2, space group P2,/n; 0„Η2ΒΝ,02 (7), triclinic, with a = 13,193(7), b = 6,871(3), c = 9,261(5) Α, α = 98,03(2), β = 102,12(2), y= 94,11(2)°, Ζ = 2, space group ΡΪ. These and other similar compounds exhibit varying contributions from the quadrupolar form (II). Correlations between structural and Ή n.m.r. data are discussed.
