(2E,3E)-3-(Pyrazin-2-yloxyimino)butan-2-one oxime.

ABSTRACT: In the title compound, C(8)H(10)N(4)O(2), all non-H atoms are nearly coplanar [maximum deviation 0.1256?(16)?Å for the methyl C furthest from the ring]. Inter-molecular O-H?N hydrogen bonds link adjacent mol-ecules into a one-dimensional zigzag chain along the c axis. There is also a weak ?-? stacking inter-action between neighbouring pyrazine rings, with a centroid-centroid distance of 4.0432?(15)?Å.

In the title compound, C(8)H(10)N(4)O(2), all non-H atoms are nearly coplanar [maximum deviation 0.1256 (16) Å for the methyl C furthest from the ring]. Inter-molecular O-H⋯N hydrogen bonds link adjacent mol-ecules into a one-dimensional zigzag chain along the c axis. There is also a weak π-π stacking inter-action between neighbouring pyrazine rings, with a centroid-centroid distance of 4.0432 (15) Å. ...[more]

Crystal structure of (1Z,2E)-cinnamaldehyde oxime.

Project description:The title compound, C9H9NO, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The conformation of the two mol-ecules differs slightly with the phenyl ring in mol-ecule A, forming a dihedral angle of 15.38?(12)° with the oxime group (O-N=C), compared to the corresponding angle of 26.29?(11)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked head-to-head by O-H?N hydrogen bonds, forming -A-B-A-B- zigzag chains along [010]. Within the chains and between neighbouring chains there are C-H?? inter-actions present, forming a three-dimensional structure.

(2Z,3E)-2-{[1-(4-Chloro-benz-yl)-1H-indol-3-yl]methyl-idene}quinuclidin-3-one oxime.

Project description:In the title compound, C(23)H(22)ClN(3)O, the benzene ring of the 4-chorobenzyl group makes a dihedral angle of 78.56 (6)° with the best plane of the indole ring.

Fluoren-9-one oxime.

Project description:In the title mol-ecule, C13H9NO, the fluorene system and the oxime group non-H atoms are essentially coplanar, with a maximum deviation from the fluorene mean plane of 0.079 (2) Å for the oxime O atom. A short intra-molecular C-H⋯O generates an S(6) ring. In the crystal, mol-ecules related by a twofold screw axis are connected by O-H⋯N hydrogen bonds, forming [100] chains Within these chains, mol-ecules related by a unit translation along [100] show π-π stacking inter-actions between their fluorene ring systems with an inter-planar distance of 3.347 (2) Å. The dihedral angle between the fluorene units of adjacent mol-ecules along the helix is 88.40 (2)°. There is a short C-H⋯π contact between the fluorene groups belonging to neighbouring chains.

4-Hydr-oxy-4,4-diphenyl-butan-2-one.

Project description:The mol-ecules of the title compound, C(16)H(16)O(2), display an intra-molecular O-H⋯O hydrogen bond between the hydroxyl donor and the ketone acceptor. Inter-molecular C-H⋯π inter-actions connect adjacent mol-ecules into chains that propagate parallel to the ac diagonal. The chains are arranged in sheets, and mol-ecules in adjacent sheets inter-act via inter-molecular O-H⋯O hydrogen bonds.

(3E,5E)-1-Benzyl-3,5-dibenzyl-idenepiperidin-4-one.

Project description:In the title compound, C(26)H(23)NO, C-H?O hydrogen bonds generate a ribbon structure along the a axis.

The benzyl-idene units adopt E configurations and the 1-benzyl group is disposed towards the 3- substituent of the piperidin-4-one ring.

Project description:In the title complex, [Ni(C?H?N?O)(NCS)(C?H?N?O)(H?O)] or [Ni(mpko)(SCN)(mpkoH)(H?O)] [where mpkoH = 1-(pyrazin-2-yl)ethanone oxime], the Ni(II) cation is in a slightly distorted octa-hedral geometry, being coordinated in the equatorial plane by four N atoms from two different mpkoH ligands, one of which is deprotonated, and by one N atom from a thio-cyanate anion and one O atom from a water mol-ecule in the axial positions. There is an intra-molecular O-H?O hydrogen bond involving the oxime units of the two ligands. In the crystal, a three-dimensional supra-molecular architecture is formed by O-H?O and O-H?N hydrogen bonds.
