4-Methyl-2,7-dioxo-3,6-dioxa-1(1,1′)-ferrocenacycloheptaphane
In the title compound, [Fe(C(15)H(14)O(4))], the two cyclo-penta-dienyl (Cp) rings are nearly parallel, making a dihedral angle of 2.6 (1)°. The distance between the centroids of the Cp rings is 3.309 (8) Å. The relative orientation of the two Cp rings is characterized by a torsion angle of -43.99 (6)° defined by the two centroids and the two substituted C atoms.
متن کاملEthyl 4-methyl-1,3-dioxo-1,2,3,4-tetrahydroisoquinoline-4-carboxylate
In the title compound, C(13)H(13)NO(4), the fused-ring system is nearly planar, with an r.m.s. deviation of 0.0408 Å. In the crystal, mol-ecules are linked into centrosymmetric dimers by a pair of N-H⋯O hydrogen bonds. The ethyl group is disordered over two positions in a ratio of 0.758 (6):0.242 (6).
متن کاملRacemic methyl 3,10-dioxa-2-azatricyclo[6.2.1.02,6]undecane-4-carboxylate
The structure of the racemic title compound, C(10)H(15)NO(4), consists of a tricyclic skeleton comprising a six-membered piperidine ring and five-membered isoxazolidine and tetra-hydro-furan rings. The piperidine ring adopts a distorted chair conformation, while the isoxazolidine and tetra-hydro-furan rings have envelope conformations.
متن کاملMethyl 2-acetamido-2-(4-hydroxy-2-methyl-1,3-dioxo-1,2,3,4-tetrahydroisoquinolin-4-yl)-4-methylpentanoate
In the isoquinoline ring system of the title mol-ecule, C(19)H(24)N(2)O(6), the N-heterocyclic ring is in a half-boat conformation. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(7) ring motif. In the crystal, mol-ecules are linked via inter-molecular bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds into a three-dimensional network.
متن کامل6-(4-Methylphenyl)-2,10-dioxo-3,9-dioxa-6-aza-1(1,1′)-ferrocenacyclodecaphane
In the title compound, [Fe(C(23)H(23)NO(4))], the two cyclo-penta-dienyl (Cp) rings are nearly parallel, with a dihedral angle of 2.1 (1)°. The distance between the centroids of the Cp rings is 3.277 (8) Å. The relative orientation of the two Cp rings is characterized by a torsion angle of -64.3 (3)° defined by the two centroids and two substituted atoms.
