6-Chloro-N'-(2-hydr-oxy-1-naphthyl-methyl-ene)nicotinohydrazide.

ABSTRACT: The title compound, C(17)H(12)ClN(3)O(2), was synthesized by the Schiff base condensation reaction of 2-hydr-oxy-1-naphthaldehyde with 6-chloro-nicotinic acid hydrazide in a methanol solution. The mol-ecule displays a trans configuration with respect to the C=N and C-N bonds. The dihedral angle between the naphthyl ring system and the pyridine ring is 7.6?(4)°. There is an intra-molecular O-H?N hydrogen bond. The crystal structure is stabilized by inter-molecular N-H?O and C-H?O hydrogen bonds, forming chains running along the b axis.

Di-n-but-yl{4-hydr-oxy-N'-[(2-oxido-1-naphthyl-?O)methyl-ene]benzo-hydrazidato-?O,N'}tin(IV).

Project description:The deprotonated Schiff base ligand in the title compound, [Sn(C(4)H(9))(2)(C(18)H(12)N(2)O(3))], O,N,O'-chelates to the Sn atom, which is five-coordinated in a cis-C(2)NO(2)Sn trigonal-bipyramidal environment. The apical sites are occupied by the O atoms [O-Sn-O = 155.2?(2)°]. The hydr-oxy group is a hydrogen-bond donor to the two-coordinate N atom of an adjacent mol-ecule, the hydrogen-bonding inter-action giving rise to a helical chain running along the c axis. The carbon atoms of the butyl chains are equally disordered over two positions.

5-Chloro-8-hydr-oxy-6-methyl-1,4-naphthoquinone.

Project description:The mol-ecule of the title compound, C(11)H(7)ClO(3), is planar, with a maximum deviation of 0.0383 (10) Å from the naphthoquinone plane. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds. Short intra-molecular Cl⋯O [2.8234 (8) Å] and O⋯O [2.5530 (11) Å], and inter-molecular Cl⋯Cl [3.2777 (3) Å] contacts further stabilize the crystal structure.

4-Chloro-7-hydr-oxy-6-methyl-1,7-naphthyridin-8(7H)-one.

Project description:The title compound, C(9)H(7)ClN(2)O(2), was prepared by reaction of methyl 4-chloro-3-(prop-1-yn-yl)picolinate with hydroxy-l-amine in MeOH/KOH solution. The two essentially planar mol-ecules which make up the asymmetric unit have almost identical geometries and and are linked into dimeric aggregates via pairs of O-H?O hydrogen bonds. These aggregates have almost perfect inversion symmetry; however, quite unusually, the inversion center of the dimer does not coincide with the crystallographic inversion center.

2-Hydr-oxy-N'-(2-methoxy-naphthyl-idene)benzohydrazide.

Project description:The title Schiff base compound, C(19)H(16)N(2)O(3), prepared by the reaction of 2-meth-oxy-1-naphthyl-aldehyde and 2-hydroxy-benzohydrazide, crystallizes with two independent mol-ecules in the asymmetric unit. Each mol-ecule exists in a trans configuration with respect to the methyl-idene group. The naphthyl ring system make dihedral angles of 65.0?(2)° and 55.8?(2)° with the planes of the benzene rings. Intra-molecular N-H?O and O-H?O hydrogen bonds help to stabilize the mol-ecular conformations. In the crystal structure, mol-ecules are linked into one-dimensional chains parallel to the c axis by inter-molecular O-H?N and O-H?O hydrogen bonds.
