The molecular PdII title complex exhibits a square-planar coordination about the central metal atom, provided by two trans-arranged chlorido ligands and two nitrogen atoms from the two neutral organic ligands.
The title complex, [PdCl2(C9H13N)2], comprises a single molecule in the asymmetric unit. The PdII atom is tetracoordinated by two N atoms from two trans-aligned organic ligands and two Cl ligands, forming a square-planar metal coordination environment. The distances from the ortho-H atoms on the phenyl ring to the central PdII atom fall within the range 4.70–5.30 Å, precluding any significant intramolecular Pd⋯H interactions.
The title compound represents the first reported example of a [1,3]oxatellurole, prepared in three steps from 3,4-dimethylphenol. Both independent molecules are folded along their Te⋯O axes, with an average angle φ = 25.1° between the Te–C–O planes and the remaining non-hydrogen atoms. A Hirshfeld plot indicates a weak intermolecular interaction between the two tellurium atoms in the asymmetric unit.
The structure of the title compound, C9H10OTe, at 100 K has orthorhombic (P21212) symmetry with two independent molecules in the asymmetric unit (Z′ = 2). The molecules are folded along their Te⋯O axes, with their Te–C–O planes angled at an average of 25.1° with respect to the remaining non-H atoms, which are almost coplanar (average deviation from planarity = 0.04 Å). A Hirshfeld plot shows weak intermolecular interactions between the two Te atoms located in each asymmetric molecule, with a Te⋯Te distance of 3.7191 (4) Å. The structure is strongly pseudosymmetric to the space group Pccn with Z′ = 1. The crystal chosen for data collection was found to be was an inversion twin.
The reaction of 4-amino 3-nitrobenzoic acid and manganese dichloride tetrahydrate in an ethanol–water mixture yielded the title complex[Mn(C7H5N2O4)2(C7H6N2O4)2(H2O)2]·2H2O. In the crystal, molecules are linked by N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds.
The manganese title complex, [Mn(C7H5N2O4)2(C7H6N2O4)2(H2O)2]·2H2O, is one of the first 4-amino 3-nitrobenzoic acid (4 A3NBA) monoligand metal complexes to be synthesized. It crystallizes in the centrosymmetric monoclinic space group P21/n with the complex molecules located on inversion centers. Four 4 A3NBA ligand molecules are monodentately coordinated by the Mn2+ ion through the carboxylic oxygen atoms while the other two positions of the inner coordination sphere are occupied by water molecules, giving rise to a distorted octahedron, and two water molecules are in the outer coordination sphere. There are two intramolecular hydrogen bonds in the complex molecule. The first is of the common N—H⋯O=N type, while the second is a rarely occurring very strong hydrogen bond in which a common proton is shared by two uncoordinated oxygen atoms of neighboring carboxylate groups. In the crystal, an intricate system of intermolecular hydrogen bonds links the complex molecules into a three-dimensional-network.
In the crystal structure of the title compound, the central zinc(II) metal atom is surrounded by two N atoms of a bidentate 4,7-methoxy-1,10-phenanthroline ligand and two chlorido ligands in a distorted tetrahedral coordination environment.
In the title complex, [ZnCl2(C14H12N2O2)], the ZnII atom is located on a twofold rotation axis and is fourfold coordinated by two chlorido ligands and a bidentate 4,7-methoxy-1,10-phenanthroline ligand in a distorted tetrahedral environment. Weak π–π stacking interactions between adjacent 4,7-dimethoxy-1,10-phenanthroline rings [centroid-to-centroid distances = 3.5969 (11) and 3.7738 (11) Å] contribute to the alignment of the complexes in layers parallel to (
A second crystalline modification of the title compound, C12H19N3S [common name: cis-jasmone thio-semicarbazone] was crystallized from tetra-hydro-furane at room temperature. There is one crystallographic independent mol-ecule in the asymmetric unit, showing disorder in the cis-jasmone chain [site-occupancy ratio = 0.590 (14):0.410 (14)]. The thio-semicarbazone entity is approximately planar, with the maximum deviation from the mean plane through the N/N/C/S/N atoms being 0.0463 (14) Å [r.m.s.d. = 0.0324 Å], while for the five-membered ring of the jasmone fragment, the maximum deviation from the mean plane through the carbon atoms amounts to 0.0465 (15) Å [r.m.s.d. = 0.0338 Å]. The mol-ecule is not planar due to the dihedral angle between these two fragments, which is 8.93 (1)°, and due to the sp 3-hybridized carbon atoms in the jasmone fragment chain. In the crystal, the mol-ecules are connected by N-H⋯S and C-H⋯S inter-actions, with graph-set motifs R 2 2(8) and R 2 1(7), building mono-periodic hydrogen-bonded ribbons along [010]. A Hirshfeld surface analysis indicates that the major contributions for the crystal cohesion are H⋯H (67.8%), H⋯S/S⋯H (15.0%), H⋯C/C⋯H (8.5%) and H⋯N/N⋯H (5.6%) [only non-disordered atoms and those with the highest s.o.f. were considered]. This work reports the second crystalline modification of the cis-jasmone thio-semicarbazone structure, the first one being published recently [Orsoni et al. (2020 ▸). Int. J. Mol. Sci. 21, 8681-8697] with the crystals obtained in ethanol at 273 K.
