In the title compound, [CdI2(C12H12N2)(C3H7NO)], the Cd(II) cation is five-coordinated in a distorted trigonal-bipyramidal configuration by two N atoms from a 4,4'-dimethyl-2,2'-bipyridine ligand, one O atom from a dimethyl-formamide ligand and two I(-) anions. π-π stacking between pyridine rings of adjacent mol-ecules [centroid-centroid distance = 3.666 (3) and 3.709 (4) Å] stabilizes the thre...
The asymmetric unit of the title complex, {[Mn(C(20)H(10)Br(2)N(3)O(5))(H(2)O)]·(CH(3))(2)NCHO}(n), consists of one Mn(III) ion, one (E)-5-bromo-N-[2-(5-bromo-2-oxidobenzyl-idene-amino)-4-nitro-phen-yl]-2-oxidobenzamidate ligand (Schiff base), one water mol-ecule and an N,N-dimethyl-formamide mol-ecule. The coordination geometry around the Mn(III) ion is a distorted octa-hedron, being surrounde...
In the title complex, [Co(C(7)H(5)O(3))(C(27)H(27)N(7))]ClO(4)·1.5C(3)H(7)NO, the Co(II) ion is five-coordinated by four N atoms from a tris-(N-methyl-benzimidazol-2-ylmeth-yl)amine (Mentb) ligand and one O atom from a salicylate ligand in a distorted trigonal-bipyramidal geometry with approximate mol-ecular C(3) symmetry. The perchlorate ion is disordered over two sites with equal occupancy. O...
In the mol-ecule of deferasirox dimethyl-formamide solvate, C(21)H(15)N(3)O(4)·C(3)H(7)NO, the central 1,2,4-triazole ring is tilted with respect to the benzoic acid and one of the 2-hy-droxy-phenyl units but coplanar with the other 2-hy-droxy-phenyl group, as indicated by the dihedral angles of 33.69 (9), 72.57 (8) and 5.18 (9)°, respectively. Intra-molecular O-H⋯N hydrogen bonds generate an S...
The centrosymmetric mol-ecule of the title complex, [Cd(4)Cl(8)(C(3)H(4)N(2))(6)(C(3)H(7)NO)(2)], contains four Cd(II) atoms, six imidazole, two dimethyl-formamide and eight chloride ligands. The structure shows a novel chloride-bridged tetra-nuclear cadmium quasi-cubane cluster. The coordination geometry of all Cd(II) atoms is distorted octa-hedral, with the two metal atoms in the asymmetric u...
The title compound, C(21)H(19)N(3)O(3)·C(3)H(7)NO, adopts an E conformation with respect to the azomethine bond and crystallizes in the amide form. The dihedral angle between the rings lined to the C=N bond is 88.60 (12)°. The dimethyl-formamide solvent mol-ecule is disordered over two orientations with site occupancies of 0.684 (3) and 0.316 (3). The two N atoms of the hydrazinecarboxamide gro...
In this work, we report synthesis of silver nanoplates by a simple reduction process of silver nitrate in the presence of polyvinyl alcohol (PVA) and N,N'-dimethyl formamide (DMF). The Characterization of the samples were carried out using X-ray diffraction (XRD), Transmission-electron microscopy (TEM) and UV-vis spectroscopy. Absorption spectra of the nanoplates in comparison with that of the ...
The title compound, [Cu(CN)(C(12)H(8)N(2))(2)](2)[Fe(CN)(5)(NO)]·C(3)H(7)NO, is formed of discrete [Cu(phen)(2)CN](+) cations (phen is 1,10-phenanthroline), nitro-prusside [Fe(CN)(5)(NO)](2-) anions and dimethyl-formamide (DMF) mol-ecules of crystallization. The metal atom has a distorted trigonal-bipyra-midal coordination environment, defined by four N atoms of two phen mol-ecules and a C atom...
The asymmetric unit of the title compound {systematic name: cis-dichloridobis[(3,7-dimethylbicyclo-[3.3.1]non-1-ylmeth-yl)-amine-κN]platinum(II) N,N-dimethyl-formamide solvate}, [PtCl(2)(C(11)H(19)N)(2)]·C(3)H(7)NO, consists of two metrically similar Pt complexes and two dimethyl-formamide solvent mol-ecules. Each Pt(II) center is coordinated by the amine groups of two (1-adamantylmeth-yl)amine...
In the title compound, C(16)H(12)N(2)O(8)·2C(3)H(7)NO, the complete tricyclic compound is generated by a crystallographic centre of symmetry. In the crystal, the tricycle is linked to two adjacent N,N-dimethyl-formamide solvent mol-ecules by O-H⋯O hydrogen bonds.
