Abstract In the two title compounds, the 2-methyl-1,3-dioxoindan-2-yl and 4-(brom; ethoxy) phenyl groups aretrans with respect to one another. The phenyl ring and the azo group are not coplanar in the two molecules. The five-membered rings of the two compounds adopt an envelope conformation. The crystallographic parameters are as follows: 2-Methyl-2-(4-bromphenylazo)-1,3-indandione (I): monoclinic, P21/a witha=8.098(2),b=14.442(2),c=12.554(1)Å, β=100.55(2)o, andD calc=1.58 g cm−3 forZ=4; 2-methyl-2-(4-ethoxyphenylazo)-1, 3-indandione (II): monoclinic, P21/a witha=8.258(2),b=14.449(1),c=13.559(2)Å, β=101.19(1)o, andD calc=1.29 g cm−3 forZ=4.
