title: Ethyl 1-(4-chloro-phen-yl)-3-[1-(4-meth-oxy-phen-yl)-4-oxo-3-phenyl-azetidin-2-yl]-2-nitro-2,3,10,10a-tetra-hydro-1H,5H-pyr-rolo[1,2-b]isoquinoline-10a-carboxyl-ate.
abstract: In the title compound, C(37)H(34)ClN(3)O(6), the pyrrolidine and piperidine rings adopt envelope and boat conformations, respectively. The β-lactam ring is planar and forms dihedral angles of 21.3 (2) and 73.9 (2)°, respectively, with the attached methoxy-phenyl and phenyl rings. Intra-molecular C-H⋯O and C-H⋯N hydrogen bonds are observed. Centrosym-metrically related mol-ecules are linked together by weak C-H⋯O hydrogen bonds to form dimers.
