2,4-Dichloro-6-nitrobenzoic acid
The title compound, C(7)H(3)Cl(2)NO(4), was prepared by the reaction of 2,4-dichloro-6-nitro-toluene with 20% HNO(3) solution at 430 K. The carboxyl and nitro groups are twisted by 82.82 (12) and 11.9 (2)°, respectively, with respect to the benzene ring. The crystal structure is stabilized by O-H⋯O hydrogen bonding between carboxyl groups and weak C-H⋯O hydrogen bonding between the nitro group ...

Background. Hox genes are implicated in hematopoietic stem cell (HSC) regulation as well as in leukemia development through translocation with the nucleoporin gene NUP98. Interestingly, an engineered NUP98-HOXA10 (NA10) fusion can induce a several hundred-fold expansion of HSCs in vitro and NA10 and the AML-associated fusion gene NUP98-HOXD13 (ND13) have a virtually indistinguishable ability to...

The title compound, C(10)H(7)Cl(2)NO, features a planar mol-ecule, excluding the methyl H atoms [maximum deviation = 0.0385 (1) Å]. The crystal packing is stabilized by π-π stacking inter-actions across inversion centres [centroid-to-centroid distance = 3.736 (3) Å].

The crystal of the title compound, [Zn(C(7)H(3)Cl(2)O(2))(2)(H(2)O)(2)](2)·[Zn(2)(C(7)H(3)Cl(2)O(2))(4)(H(2)O)(2)], consists of monomeric and dimeric Zn(II) complexes. Both complexes afford a six-coordinated coordination environment about the Zn atoms with cis-configuration ligands. The deprotonated hydr-oxy groups of the 3,5-dichloro-salicylaldehyde ligands bridge two metal cations, forming a ...
متن کامل3,5-Dichloro-6-methylpyridin-2-amine
In the title compound, C(6)H(6)Cl(2)N(2), intra-molecular N-H⋯Cl and C-H⋯Cl contacts generate five-membered rings, producing S(5) ring motifs. Pairs of inter-molecular N-H⋯N hydrogen bonds link neighbouring mol-ecules into dimers with R(2) (2)(8) ring motifs. In the crystal structure, these dimers are connected by N-H⋯Cl inter-actions and are packed into columns.
