Abstract

The formula of the title compound is C16H27ClN2O5,MW = 362.9 orthorhombic,P212121,a = 8.403(1),b= 13.133(1),c= 15.972(2) Å,Z = 4,D x = 1.37 g cm−3, μ (CuKα) = 2.2 mm-1. The lupanine skeleton has atrans-trans configuration. The ringA has a half-chair conformation, theB andD rings adopt a chair form, and theC ring forms a boat. The lupanine cations are linked together by the intermolecular hydrogen bonds

forming infinite chains alongb. The N(16) ... O(C2) distance is 2.763(7) Å.
