and V615, Table ), single petals cut from double-decker flowers (48 h) (cif files V614b and V626, Table ), a hexagonal crystal after 4 h of reaction time (cif file V637, Table ), and a flower after 6 h of reaction time (cif files V651 and V653, Table ) were used for single-crystal X-ray analyses. Crystals from several different batches were analyzed both for entire double-decker flowers and the separated petals. The crystals were flash frozen in the liquid nitrogen gaseous stream of an OxfordSystems Cryosystem. Diffraction data were collected with CuKα1 λ = 1.54184
