The title compound, (C(2)H(8)N)(C(5)H(12)NO)[ZnCl(4)], was synthesized by hydro-thermal reaction of ZnCl(2) with 4-methyl-morpholine in a dimethyl-formamide solution. The asymmetric unit is composed of half a [ZnCl(4)](2-) anion, half a 4-methyl-morpholin-4-ium cation and half a dimethyl-ammonium cation, all located on mirror planes parallel to ac. All the amine H atoms are involved in inter-mo...

Organic solvents used for solubilization of the substrates/NCEs are known to affect the activity of cytochrome P450 enzymes. Further, this effect varies with the solvents used, the substrates and CYP450 isoforms in question. In the present study, we have investigated the effect of ten commonly used water miscible organic solvents (methanol, ethanol, 1-propanol, 2-propanol, acetonitrile, acetone...

Solubility of lornoxicam in various pure solvents and solvent-cosolvent mixtures was studied to understand drug vehicle interactions and in order to get the required solubility equal to the dose of lornoxicam, i.e., 4 mg/ml for development of solution formulation. Polyethylene glycol (PEG) 400, propylene glycol, ethanol, water, dimethyl formamide, dimethyl sulfoxide, and ethyl acetate were used...

In this study silver/poly vinyl alcohol (PVA) and silver/poly vinyl pyrrolidone (PVP) Nanocomposites were prepared via reduction of silver salt by employing DMF (N, N`- dimethyl formamide) as a reducing agent. Effects of protective agents such as PVA and PVP were also described here. We show that the acidic pH of PVP solution also affects the interaction between protective agents and silver nan...

In the title compound, C(28)H(18)O(4)·2C(3)H(7)NO, the dihedral angle between the benzene rings and the anthracene system is 74.05 (12)°. A crystallographic inversion centre is located in the middle of the anthracene unit. The dimethyl-formamide solvent mol-ecules are partially disordered over two positions of approximately equal occupancy [0.529 (6):0.471 (6)]. Inter-molecular O-H⋯O hydrogen b...

In the title coordination polymer, [Co(C(7)H(4)N(3)O(2))(2)(C(3)H(7)NO)](n), the Co(II) atom is five-coordinated in a distorted square-pyramidal CoON(4) geometry with the O atom from a dimethyl-formamide mol-ecule in an equatorial position. The bridging phenyl-cyanamide anions generate an infinite chain propagating in [001].

In the title compound, [Cu(C(14)H(10)N(3)O)(2)(C(3)H(7)NO)], the Cu(II) atom is five-coordinated by two N,O-bidentate 2-benzamido-benzimidazolate anions and one O-coordinated dimethyl-formamide (DMF) mol-ecule, resulting in a distorted square-based pyramidal CuN(2)O(3) geometry for the metal atom, with the DMF O atom at the apical site. In the crystal structure, inter-molecular N-H⋯N hydrogen b...
