✦ Synopsis

Crystals of the title compound, C 17 H 30 N 2 O 7 , were successfully grown from ethyl acetate at room temperature. In the crystal structure, a free carboxylic acid group is found at the terminal C atom. The free acid ÐOH group contributes to a hydrogenbond network, together with two NÐHÁ Á ÁO interactions, forming tight packing.
