✦ Synopsis

The title compound, C 54 H 66 N 2 O 4 , crystallizes with two molecules in the asymmetric unit. Both adopt the typical partial cone conformation which was also found for 26,28-diallyloxy-5,17-di-tert-butyl-25,27-bis(cyanomethoxy)-11,23-dinitrocalix[4]arene [Danila, Bo ¨hmer & Bolte (2005). Org. Biomol. Chem. 3,[3508][3509][3510][3511][3512][3513]. The crystal structure of the title compound in the 1,2-alternate conformation has been determined recently [Danila, Bo ¨hmer & Bolte (2005). Org. Biomol. Chem. 3,[3508][3509][3510][3511][3512][3513].
