3,5-Dimethyl-pyrazolium 3,5-dinitro-salicylate.

ABSTRACT: In the title mol-ecular salt, C(5)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the roughly planar anion (r.m.s. deviation = 0.120?Å) has been deprotonated at the phenol group. An intra-molecular O-H?O hydrogen bond in the anion generates an S(6) ring. In the crystal, the components are linked by cation-to-anion N-H?O and N-H?(O,O) hydrogen bonds, generating [010] double chains. Weak C-H?O inter-actions consolidate the packing.

In the title mol-ecular salt, C(5)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the roughly planar anion (r.m.s. deviation = 0.120 Å) has been deprotonated at the phenol group. An intra-molecular O-H⋯O hydrogen bond in the anion generates an S(6) ring. In the crystal, the components are linked by cation-to-anion N-H⋯O and N-H⋯(O,O) hydrogen bonds, generating [010] double chains. Weak C-H⋯O inter-actions consolidate the packing. ...[more]

Cinnarizinium 3,5-dinitro-salicylate.

Project description:THE TITLE COMPOUND [SYSTEMATIC NAME: 4-diphenyl-methyl-1-(3-phenylprop-2-en-1-yl)-piperazin-1-ium 2-carb-oxy-4,6-dinitro-pheno-late], C(26)H(29)N(2) (+)·C(7)H(3)N(2)O(7) (-), is the dinitro-salicylate salt of a tertiary amine. Deprotonation of the carb-oxy-lic acid group occurred on the phenolic hy-droxy group. The diaza-cyclo-hexane ring adopts a chair conformation. Intra-molecular O-H?O and inter-molecular C-H?O and N-H?O hydrogen bonds are observed. The N-H?O hydrogen bonds are bifurcated at the H atom and connect the cinnarizinium and 3,5-dinitro-salicylate ions together. Inter-molecular C-H?O hydrogen bonds connect the components into layers perpendicular to the crystallographic a axis.

A co-crystal of 3-(3,5-dinitro-benzo-yl)-1,1-dimethyl-thio-urea and N,N-dimethyl-3,5-dinitro-benzamide.

Project description:In the title compound, C(10)H(10)N(4)O(5)S·C(9)H(9)N(3)O(5), the amide groups of 3-(3,5-dinitro-benzo-yl)-1,1-dimethyl-thio-urea and N,N-dimethyl-3,5-dinitro-benzamide mol-ecules are oriented at dihedral angles of 39.13?(8) and 55.97?(11)°, respectively, to the attached benzene rings. In the crystal, the two mol-ecules are linked by an N-H?O hydrogen bond. Weak C-H?O link the mol-ecules into a sheet parallel to the bc plane. C-H?S inter-actions also occur.

2-Amino-4,6-dimethyl-pyrimidinium 3,5-dinitro-benzoate dihydrate.

Project description:In the title compound, C(6)H(10)N(3) (+)·C(7)H(3)N(2)O(6) (-)·2H(2)O, the amino-pyrimidine mol-ecule is protonated at one of the pyrimidine N atoms. The carboxyl-ate group of the 3,5-dinitro-benzoate anion inter-acts with the protonated pyrimidine N atom and the 2-amino group through a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) motif. Two inversion-related pyrimidine rings are linked via a pair of N-H⋯N hydrogen bonds, also forming an R(2) (2)(8) ring motif.

Poly[(?-3,5-dinitro-benzoato)(?-3,5-dinitro-benzoic acid)rubidium].

Project description:The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(6))(C(7)H(4)N(2)O(6))](n), comprises an Rb(+) cation, a 3,5-dinitro-benzoate anion and a 3,5-dinitro-benzoic acid ligand. The Rb(+) cation is nine-coordinated by O atoms from four 3,5-dinitro-benzoate anions and three neutral 3,5-dinitro-benzoic acid ligands. The metal atom is firstly linked by four bridging carboxyl groups, forming a binuclear motif, which is further linked by the nitro groups into a two-dimensional framework along the [110] direction. A short O-H?O hydrogen bond between two adjacent carboxy/carboxylate groups occurs.

(Dimethyl sulfoxide-?O)trimeth-yl(2-methyl-3,5-dinitro-benzoato-?O)tin(IV).

Project description:In the title mononuclear complex, [Sn(CH(3))(3)(C(7)H(5)N(2)O(6))(C(2)H(6)OS)], the Sn(IV) ion is coordinated by three methyl groups in the equatorial plane, and by an O atom from a 2-methyl-3,5-dinitrobenzoate ligand and a dimethyl sulfoxide ligand in the axial sites, to form a slightly distorted trigonal-bipyramidal environment. The O atoms of one of the nitro groups are disordered over two sets of sites, with refined occupancies of 0.55?(4) and 0.45?(4). The closest inter-molecular inter-action is a weak C-H?O hydrogen bond.

Bis[6-(3,5-dimethyl-1H-pyrazol-1-yl-κN)picolinato-κN,O]manganese(II) bis-(3,5-dinitro-benzoic acid) solvate.

Project description:In the title complex, [Mn(C(11)H(10)N(3)O(2))(2)]·2C(7)H(4)N(2)O(6), the Mn(II) atom has a disorted octa-hedral coordination formed by four N and two O atoms of two mer-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands (DMPP). Each of the two symmetry-independent 3,5-dinitro-benzoic acid mol-ecules is linked to the mol-ecule of the complex via a hydrogen bond involving its carboxylic H atom and one of the DMPP ligands of the complex. However, in one of the DMPP ligands, the non-coordinated carbonyl O atom serves as the hydrogen-bond acceptor, whereas in the second ligand it is the Mn-coordinated O atom which is involved in the hydrogen bonding.
