2(3),9(10),16(17),23(24)-tetrakis-2,6-dimethoxyphenoxy substituted magnesium (II) phthalocyanine, which has very good solubility in polar and non-polar solvents does not aggregate, was synthesized. Its structure characterized by spectroscopic methods such as elemental analysis, UV-vis, FT-IR, MALDI-TOF mass 1H NMR. It aprotic dimethyl sulfoxide, N, N- Dimethylformamide, tetrahydrofuran, dichlor...

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 ...

In the title compound, C(13)H(14)N(4)O·C(3)H(7)NO, a 1,5-phenyl-carbonohydrazide mol-ecule cocrystallizes with an N,N-dimethyl-formamide mol-ecule. In the 1,5-phenyl-carbonohydrazide mol-ecule, the two phenyl rings are twisted by an angle of 45.8 (5)°. Inter-molecular N-H⋯O hydrogen bonds and weak inter-molecular C-H⋯O inter-actions contribute to a supra-molecular two-dimensional network in the...

The title compound, C(17)H(15)NO(2), was synthesized by reaction of 1,2-dibromo-ethane with 1-benzoyl-N-phenyl-cyclo-propane-carboxamide and K(2)CO(3) in dimethyl-formamide. The mol-ecule exhibits a V-shaped conformation in the crystal with a dihedral angle of 88.7 (3)° between the two benzene rings. Pairs of N-H⋯O hydrogen bonds link the mol-ecules into dimers about centres of inversion.

The title compound, 3C(14)H(12)N(2)O(2)·C(3)H(7)NO, was synthesized by reaction of benzoyl chloride with hydrazine hydrate under microwave irradition. The asymmetric unit comprises three 1,2-dibenzoyl-hydrazine mol-ecules and one dimethyl-formamide mol-ecule. The 1,2-dibenzoyl-hydrazine mol-ecules are linked by pairs of N-H⋯O hydrogen bonds into chains propagating along [010].

In the title compound, C(27)H(15)Br(2)ClO·C(3)H(7)NO, the xanthene moiety has a flattened boat conformation with a folding angle between the naphthalene units of 9.46 (3)°. The mean planes of the xanthene system and its 4-chloro-phenyl substituent are nearly perpendicular [dihedral angle = 89.43 (5)°]. The dimethyl-formamide solvent mol-ecule is disordered over two sets of sites with an occupan...

In the title compound, C(13)H(8)N(2)O(2), prepared from furfuryl alcohol and 4-nitro-phthalonitrile in the presence of potassium carbonate in dimethyl-formamide, the furan and benzene rings are oriented at a dihedral angle of 53.45 (9)°. In the crystal, weak C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules into a three-dimensional network.

The title complex, [NiCl(2)(C(15)H(24)N(6))(C(3)H(7)NO)], is isomorphous with the Co(II) analogue. Three N-atom donors from the facially coordinating triaza macrocyclic ligand, one O-atom donor from dimethyl-formamide and two Cl(-) anions surround the Ni(II) ion in a distorted octa-hedral coordination geometry. Inter-molecular C-H⋯Cl and C-H⋯N hydrogen-bonding inter-actions link the complex mol...
