2-(2-Hydroxy-ethyl)phthalazin-1(2H)-one.

ABSTRACT: In the mol-ecule of the title compound, C(10)H(10)N(2)O(2), the rings are nearly coplanar, making a dihedral angle of 2.35?(5)°. In the crystal structure, inter-molecular C-H?O, C-H?N and O-H?O hydrogen bonds link the mol-ecules, generating R(4) (4)(22) and R(4) (4)(24) ring motifs to form a three-dimensional network. A weak ?-? inter-action between the pyridazinone and benzene rings further stabilizes the crystal structure, with a centroid-centroid distance of 3.709?(3)?Å and an inter-planar separation of 3.312?Å.

In the mol-ecule of the title compound, C(10)H(10)N(2)O(2), the rings are nearly coplanar, making a dihedral angle of 2.35 (5)°. In the crystal structure, inter-molecular C-H⋯O, C-H⋯N and O-H⋯O hydrogen bonds link the mol-ecules, generating R(4) (4)(22) and R(4) (4)(24) ring motifs to form a three-dimensional network. A weak π-π inter-action between the pyridazinone and benzene rings further stabilizes the crystal structure, with a centroid-centroid distance of 3.709 (3) Å and an inter-planar se ...[more]

Project description:In the crystal structure of the title compound, C(12)H(14)N(2)O(3), mol-ecules are packed into layers parallel to (100). Each layer contains centrosymmetric dimers formed by a pair of strong O-H⋯N hydrogen bonds with an R(2) (2)(10) motif, while strong O-H⋯O hydrogen bonds forming C(10) chains connect mol-ecules into a two-dimensional network. Additional stabilization is supplied by weak C-H⋯O hydrogen bonds and weak π-π stacking inter-actions with centroid-centroid distances in the range 3.4220 (7)-3.9616 (7) Å.

5-Ethyl-4-methyl-1H-pyrazol-3(2H)-one.

Project description:In the title compound, C(6)H(10)N(2)O, the 2,3-dihydro-1H-pyrazole ring is approximately planar, with a maximum deviation of 0.013 (1) Å. Pairs of inter-molecular N-H⋯O hydrogen bonds link neighboring mol-ecules into dimers, generating R(2) (2)(8) ring motifs. These dimers are further linked into two-dimensional arrays parallel to the bc plane by inter-molecular N-H⋯O hydrogen bonds. The crystal structure is further stabilized by C-H⋯π inter-actions.

5-Ethyl-4-phenyl-1H-pyrazol-3(2H)-one.

Project description:The asymmetric unit of the title compound, C(11)H(12)N(2)O, consists of two crystallographically independent mol-ecules (A and B) with similar geometries. Both mol-ecules exist in a keto form, the C=O bond length being 1.286 (2) Å in A and 1.283 (2) Å in B. The dihedral angles between the pyrazole ring and the attached phenyl ring are 43.28 (12) and 46.88 (11)°, respectively, for A and B. The ethyl unit in mol-ecule B is disordered over two positions with a site-occupancy ratio of 0.508 (5):0.492 (5). In the crystal, each of the independent mol-ecules forms a centrosymmetric dimer with an R(2) (2)(8) ring motif through a pair of N-H⋯O hydrogen bonds. These dimers are further connected into a three-dimensional network by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds. Inter-molecular C-H⋯π inter-actions are also present.

Project description:In the title mol-ecule, C(12)H(10)Br(3)NO(2), the 2H-chromen ring is essentially planar (r.m.s. deviation = 0.022 Å) with the ethyl-amino group oriented at 13.9 (5)° with respect to the ring. The mol-ecular structure is stabilized by intra-molecular N-H⋯Br and C-H⋯Br interactions.
