Ethyl 7-pivaloyl-amino-1,8-naphthyridine-2-carboxyl-ate sesquihydrate.

ABSTRACT: In the title hydrate, C(16)H(19)N(3)O(3)·1.5H(2)O, both water mol-ecules are disordered: one over two adjacent sites in a 0.498?(5):0.502?(5) ratio and one lying near a crystallographic twofold axis. The dihedral angle between the pyridine rings of the organic moleucle is 1.47?(6)°. In the crystal, the components are linked by N-H?O, O-H?N and C-H?O hydrogen bonds, forming sheets lying parallel to the ac plane.

In the title hydrate, C(16)H(19)N(3)O(3)·1.5H(2)O, both water mol-ecules are disordered: one over two adjacent sites in a 0.498 (5):0.502 (5) ratio and one lying near a crystallographic twofold axis. The dihedral angle between the pyridine rings of the organic moleucle is 1.47 (6)°. In the crystal, the components are linked by N-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds, forming sheets lying parallel to the ac plane. ...[more]

Methyl 1-ethyl-7-methyl-4-oxo-1,4-di-hydro-1,8-naphthyridine-3-carboxyl-ate monohydrate.

Project description:In the structure of the title compound, C(13)H(14)N(2)O(3)·H(2)O, all atoms of the organic molecule except the terminal methyl group of the ethyl group attached to the N atom of the pyridinone ring are roughly coplanar, with an r.m.s. deviation of 0.0897?Å. In the crystal, C-H?O contacts link pairs of naphthyridine mol-ecules into head-to-tail dimers. These are joined by strong O-H?O hydrogen bonds from the water molecules into infinite chains along the a axis.

2-Amino-4-methyl-pyridinium 6-carb-oxy-pyridine-2-carboxyl-ate sesquihydrate.

Project description:In the title compound, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·1.5H(2)O, extensive O-H?O, O-H?N, N-H?O and C-H?O hydrogen bonds, as well as ion pairing, ?-? stacking inter-actions [centroid-centroid distances = 3.4690?(8) and 3.6932?(8)?Å between aromatic rings] occur in the crystal. There are hydrogen-bonding inter-actions between water mol-ecules, which result in cyclic tetra-meric water clusters. One of the water O molecules has half occupancy. In the anion molecules, the -CO(2) and -CO(2)H groups make torsion angles of 1.73?(18) and -12.14?(18)° with respect to the ring.

Ethyl 5-(4-amino-phen-yl)isoxazole-3-carboxyl-ate.

Project description:The asymmetric unit of the title compound, C(12)H(12)N(2)O(3), contains two mol-ecules in which the benzene and isoxazole rings are almost coplanar, the dihedral angles between their mean planes being 1.76?(9) and 5.85?(8)°. The two mol-ecules inter-act with each other via N-H?N and N-H?O hydrogen bonds, which link the mol-ecules into layers parallel to the ac plane. The layers stack in a parallel mode with an inter-layer distance of 3.36?(7)?Å.

Ethyl 2-amino-4,5-dimethyl-thio-phene-3-carboxyl-ate.

Project description:In the title compound, C(9)H(13)NO(2)S, the mean planes of thio-phene ring [maximum deviation = 0.0042 (10) Å] and eth-oxy-carbonyl group [0.0242 (15) Å] are almost coplanar [dihedral angle between them = 0.68 (11)°]. The H atoms of the two methyl groups attached to the thio-phene ring are each disordered over two orientations with site-occupancy ratios of 0.77 (4):0.23 (4) and 0.84 (4):0.16 (4). An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into an infinite wave-like chain running parallel to the b-axis direction. The crystal structure also features C-H⋯π inter-actions.

Bis(7-amino-2,4-dimethyl-1,8-naphthyridine)dinitratocadmium(II).

Project description:In the title compound, [Cd(NO(3))(2)(C(10)H(11)N(3))(2)], two naph-thyridine ring systems are coordinated to the Cd ion through the two N atoms in a bidentate chelating mode, whereas the remaining coordination sites are occupied by two O atoms from two different nitrate groups to complete the octahedral geometry. Inter-moleular N-H?O hydrogen bonds link the mol-ecules to form a one-dimensionnal sheet parallel to the ac plane. Weak slipped ?-? stacking involving the naphthyridine ring systems stabilizes the structure.
