26,28-Diallyloxy-5,11,17,23-tetra-tert-butyl-25,27-bis(cyanomethoxy)calix[4]arene in the partial cone conformation

2006

The title compound, C54H66N2O4, 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, Bohmer & Bolte (2005). Org. Biomol. Chem. 3, 3508–3513]. The crystal structure of the title compound in the 1,2-alternate conformation has been determined recently [Danila, Bohmer & Bolte (2005). Org. Biomol. Chem. 3, 3508–3513].
