Crystal structure of ?-ethyl-l-glutamate N-carb-oxy anhydride.

ABSTRACT: In the title compound (alternative name N-carboxy-l-glutamic anhydride ?-ethyl ester), C8H11NO5, the oxazolidine ring is essentially planar, with a maximum deviation of 0.019?(2)?Å. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds between the imino group and the carbonyl O atom in the ethyl ester group, forming a tape structure along the c-axis direction. The oxazolidine rings of adjacent tapes are arranged into a layer parallel to the ac plane. This arrangement is favourable for the polymerization of the title compound in the solid state.

Crystal structure of ?-methyl l-glutamate N-carb-oxy anhydride.

Project description:In the title compound, C7H9NO5, alternative name N-carb-oxy-l-glutamic anhydride ?-methyl ester, the oxazolidine ring is essentially planar with a maximum deviation of 0.020?(3)?Å. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds between the imino group and the carbonyl O atom in the methyl ester group, forming a tape structure along the a-axis direction. The tapes are linked by C-H?O inter-actions into a sheet parallel to the ac plane. The tapes are also stacked along the b axis with short contacts between the oxazolidine rings [C?O contact distances = 2.808?(4)-3.060?(4)?Å], so that the oxazolidine rings are arranged in a layer parallel to the ab plane. This arrangement of the oxazolidine rings is very preferable for the polymerization of the title compound in the solid state.

Crystal structure of <i>O</i>-benzyl-l-tyrosine <i>N</i>-carb-oxy anhydride.

Project description:In the title compound, C17H15NO4 (alternative name; O-benzyl-l-tyrosine N-carb-oxy anhydride), the oxazolidine ring is planer, with an r.m.s. deviation of 0.039 Å. The benz-yloxy and benzyl rings are almost coplanar, making a dihedral angle of 0.078 (10)°, and are inclined to the oxazolidine ring by 59.16 (11) and 58.42 (11)°, respectively. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming ribbons propagating along [010]. The ribbons are linked by C-H⋯π inter-actions, forming a three-dimensional supra-molecular structure. The oxazolidine rings of adjacent ribbons are arranged into a layer parallel to the ab plane. This arrangement is favourable for the polymerization of the compound in the solid state.

Crystal structure of memantine-carb-oxy-borane.

Project description:The synthesis and crystal structure of the title compound, C13H24BNO2 [systematic name: 3,5-di-methyl-adamantanyl-amine-borane-carb-oxy-lic acid or N-(carb-oxy-boranyl-idene)-3,5-di-methyl-adamantan-1-amine], derived from the anti-Alzheimer's disease drug memantine is reported. The C-N-B-CO2 unit is almost planar (r.m.s. deviation = 0.095 Å). The extended structure shows typical carb-oxy-lic acid inversion dimers linked by pairwise O-H⋯O hydrogen bonds [O⋯O = 2.662 (3) Å]. The amino group forms a weak N-H⋯O hydrogen bond [N⋯O = 3.011 (3) Å], linking the dimers into [001] chains in the crystal. Highly disordered solvent mol-ecules were treated using the SQUEEZE routine of PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18], which treats the electron density as a diffuse contribution without assignment of specific atom locations. A scattering contribution of 255 electrons was removed. The crystal studied was refined as a two-component twin.

Syntheses and crystal structures of 2,2,5-trimethyl-1,3-dioxane-5-carb-oxy-lic acid and 2,2,5-trimethyl-1,3-dioxane-5-carb-oxy-lic anhydride.

Project description:In 2,2,5-trimethyl-1,3-dioxane-5-carb-oxy-lic acid, C8H14O4, the carboxyl group occupies an equatorial position on the 1,3-dioxane ring. In the crystal, O-H⋯O hydrogen bonds form chains of mol-ecules, which are linked into a three-dimensional network by C-H⋯O hydrogen bonds. The asymmetric unit of 2,2,5-trimethyl-1,3-dioxane-5-carb-oxy-lic anhydride, C16H26O7, consists of two independent mol-ecules, which are linked by C-H⋯O hydrogen bonds. In the crystal, these units are connected into corrugated layers two mol-ecules thick and parallel to the ab plane by additional C-H⋯O hydrogen bonds.

Crystal structure of 5-[(4-carb-oxy-benz-yl)-oxy]isophthalic acid.

Project description:The mol-ecular shape of the title compound, C16H12O7, is bent around the central CH2-O bond. The two benzene rings are almost perpendicular to one another, making a dihedral angle of 87.78?(7)°. In the crystal, each mol-ecule is linked to three others by three pairs of O-H?O hydrogen bonds, forming undulating sheets parallel to the bc plane and enclosing R 2 (2)(8) ring motifs. The sheets are linked by C-H?O hydrogen bonds and C-H?? inter-actions, forming a three-dimensional network.

Crystal structure of 4-oxo-4H-chromene-3-carb-oxy-lic acid.

Project description:In the title compound, C10H6O4, also known as 3-carb-oxy-chromone, the non-H atoms of the chromone ring are essentially coplanar (r.m.s. deviation = 0.0057 Å), with the maximum deviation from their least-squares plane [0.011 (2) Å] being for a pyran C atom. The dihedral angle between the fused ring and plane of the carb-oxy group is 3.06 (2)°. An intra-molecular hydrogen bond is formed between the ring carbonyl O atom and the carb-oxy O-H atom, closing an S(6) loop. In the crystal, mol-ecules are assembled by stacking inter-actions [centroid-centroid distance between the benzene and pyran rings = 3.844 (3) Å] and C-H⋯O hydrogen bonds, generating a three-dimensional network. Short contacts are also observed between the carb-oxy O and C atoms [C=O⋯C=O = 3.002 (3) Å].

Redetermined crystal structure of N-(β-carb-oxy-eth-yl)-α-isoleucine.

Project description:Redetermination of the crystal structure of N-(β-carb-oxy-eth-yl)-α-isoleucine, C9H18N2O3, reported earlier by Nehls et al. [Acta Cryst. (2013), E69, o172-o173], was undertaken in which the ionization state assigned to the mol-ecule as unionized has been modified as zwitterionic in the present work. Single-crystal X-ray intensity data obtained from freshly grown crystals and freely refining the amino H atoms provide enhanced refinement and structural parameters, particularly the hydrogen-bonding scheme. N-H⋯O hydrogen bonds dominate the inter-molecular inter-actions along with a C-H⋯O hydrogen bond. The inter-molecular inter-action pattern is a three-dimensional network. The structure was refined as a two-component perfect inversion twin.

Project description:The structure of the title salt, (C5H7N2)[Fe(C6H4O2)(C6H5O2)], consists of 3-amino-pyridinium cations and 1'-carb-oxy-ferrocene-1-carboxyl-ate monoanions. The ferrocenyl moiety of the anion adopts a typical sandwich structure, with Fe-C distances in the range 2.0270?(15)-2.0568?(17)?Å. The anion possesses an eclipsed conformation, with the torsion angle ? (Csubst-Cpcent-Cpcent- Csubst) equal to 66.0°. The conformations of other 1'-carb-oxy-ferrocene-1-carboxyl-ate monoanions are compared and analyzed on the basis of literature data.
