2-(4-Meth-oxy-phen-oxy)acetohydrazide.

Project description:The title compound, C(9)H(12)N(2)O(3), was synthesized by the reaction of ethyl 2-(4-meth-oxy-phen-oxy)acetate with hydrazine hydrate in ethanol. In the acetohydrazide group, the N-N bond is relatively short [1.413?(2)?Å], suggesting some degree of electronic delocalization in the mol-ecule. In the crystal, mol-ecules are linked into sheets lying parallel to the ab plane by N-H?N and N-H?O hydrogen bonds.

Project description:In the title compound, C18H21N3O2, the dihedral angle between the benzene rings is 68.85?(11)°. In the crystal, the mol-ecules are linked by C-H?O and N-H?O hydrogen bonds, as well as weak C-H?? contacts, forming a three-dimensional supra-molecular architecture.

2-[5-Methyl-2-(propan-2-yl)phen-oxy]-N'-{2-[5-methyl-2-(propan-2-yl)phen-oxy]acet-yl}acetohydrazide.

Project description:The complete mol-ecule of the title compound, C(24)H(32)N(2)O(4), is generated by a crystallographic inversion center. The 1,2-diethyl-hydrazine moiety is nearly planar, with a maximum deviation of 0.024 (1) Å, and is inclined at a dihedral angle of 54.20 (4)° with the phenyl ring. In the crystal, [001] chains are formed, with adjacent mol-ecules in the chain linked by pair of inter-molecular N-H⋯O hydrogen bonds, generating R(2) (2)(10) ring motifs. Inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions are also observed.

2-(4-Chloro-phen-oxy)acetohydrazide.

Project description:In the title compound, C(8)H(9)ClN(2)O(2), the two planar fragments, i.e. the chloro-phenyl and C-C(=O)-N groups, are inclined at 14.93?(17)°. In the crystal, relatively weak inter-molecular N-H?N, C-H?O and N-H?O hydrogen bonds connect the mol-ecules into layers. The hydro-phobic parts of mol-ecules stick outside these layers and are connected with the neighbouring layers only by van der Waals contacts and Cl?Cl inter-actions [3.406?(2)?Å].

2-(2-Chloro-phen-oxy)acetohydrazide.

Project description:In the title compound, C(8)H(9)ClN(2)O(2), the acetohydrazide group is approximately planar, with the maximum deviation of 0.031?(2)?Å. In the crystal, the mol-ecules are linked by N-H?N, N-H?O and C-H?O hydrogen bonds, with the acetohydrazide O atom accepting two C-H?O links and one N-H?O link. This results in infinite sheets lying parallel to (100).

(E)-2-(4-Chloro-phen-oxy)-N'-(pyridin-4-yl-methyl-idene)acetohydrazide.

Project description:In the title compound, C14H12ClN3O2, the acyl-hydrazone base [C(=O)-N-N=C] is essentially planar, with an r.m.s. deviation of 0.0095?Å, and makes a dihedral angle of 12.52?(10)°with the pyridine ring. In the crystal, molecules are linked via pairs of N-H?O hydrogen bonds, forming inversion dimers with an R2(2)(8) graph-set motif. The dimers are linked via C-H?? interactions forming chains along [101].

2-(4-Chloro-phen-oxy)-N'-[2-(4-chloro-phen-oxy)acet-yl]acetohydrazide monohydrate.

Project description:In the title compound, C(16)H(14)Cl(2)N(2)O(4)·H(2)O, the hydrazine and water mol-ecules are both located on twofold axes. The C-N-N-C torsion angle is -72.66?(1)° and the dihedral angle between the two benzene rings is 67.33?(1)°. In the crystal, mol-ecules are linked into a layer structure by a combination of O-H?O, N-H?O and C-H?O hydrogen bonds. Adjacent layers are linked into a three-dimensional network by Cl?Cl inter-actions [3.400?(2)?Å]. C-H?? inter-actions are also observed.

N,N'-Diacetyl-N'-[(4-nitro-phen-oxy)acetyl]acetohydrazide.

Project description:The asymmetric unit of the title compound, C(14)H(15)N(3)O(7), contains two independent mol-ecules which are linked into a pseudocentrosymmetric dimer by a ?-? inter-action, as shown by the short distance of 3.722?(5)?Å between the centroids of the benzene rings. An extensive network of weak inter-molecular C-H?O hydrogen bonds helps to stabilize the crystal packing.
