MIPs was synthesized through microwave assisted organic synthesis (MAOS) method by using methyl methacrylate (MMA) as functional monomer, ethylene glycol dimethacrylate (EGDMA) cross-linker, benzoyl peroxide (BPO) initiator, N,N-dimethyl formamide (DMF) porogen solvent, and (HA) template. The successfully according to the characterization Fourier transform infrared (FTIR) spectroscopy, scanning...
The reaction of 5-nitrobenzimidazolone with phenoxyethyl bromide in presence of potassium carbonate in dimethyl formamide obtained 6-nitro-1,3-bis(2-phenoxyethyl)-1,3-dihydro-2H-benzimidazol-2-one. It was reduced using stannous chloride to get 6-amino -1,3-bis(2-phenoxyethyl)-1, 3-dihydro-2H-benzimidazol -2-one, which was further treated with aromatic sulphonyl chloride to obtain benzimidazolon...
The title compound, [Mn(C(3)H(7)NO)(6)][Cr(NCS)(5)(C(3)H(7)NO)], was obtained unintentionally as a product of an attempted synthesis of heterometallic complexes based on Reineckes anion using manganese powder, Reineckes salt and 1-(2-hy-droxy-eth-yl)tetra-zole as starting materials. The crystal structure of the complex consists of an [Mn(dmf)(6)](2+) cation and a [Cr(NCS)(5)(dmf)](2-) anion (dm...
THE STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: (3S,6S)-3-(4-hydroxy-benz-yl)-6-(1H-indol-3-ylmeth-yl)piperazine-2,5-dione dimethyl-formamide solvate], C(20)H(19)N(3)O(3)·C(3)H(7)NO, contains hydrogen-bonded tapes typical for diketopiperazines. The structure is stabilized by strong inter-molecular inter-actions of the types O-H⋯O and N-H⋯O involving the dipeptide and the solvent mol-ecule...
The title compound, [Zn(2)Cl(4)(C(12)H(14)N(4))(2)]·2C(3)H(7)NO, is located on a centre of inversion with one half of a complex mol-ecule and one dimethyl-formamide solvent mol-ecule in the asymmetric unit. The Zn(II) ion is tetra-hedrally coordinated by two organic ligands and two chloride ions. Each organic ligand acts as a bidentate ligand, connecting two Zn(II) ions, resulting in a dimeric ...
The asymmetric unit of the title compound, C(14)H(8)N(2)O(8)·2C(3)H(7)NO or L·2DMF (DMF = N,N-dimethyl-formamide), contains one half of the centrosymmetric mol-ecule L and one solvent mol-ecule, which is disordered between two orientations in a 0.555 (4):0.445 (4) ratio. Inter-molecular O-H⋯O hydrogen bonds link one L and two DMF mol-ecules into a centrosymmetric hydrogen-bonded cluster. The cr...
The title compound, [Ni(2)(C(12)H(12)N(2)O(4)S(3))(H(2)O)(4)]·2C(3)H(7)NO·3H(2)O, is made up of a centrosymmetric, bimetallic complex containing a 24-membered macrocyclic ring, two dimethyl-formamide and three water solvent mol-ecules. The Ni atom adopts a slightly distorted NiO(6) octahedral geometry arising from two O,O-bidentate ligands and two water molecules. There are inter-molecular O-H⋯...
In the title compound, C(14)H(9)Cl(2)N(3)O(3)S·C(3)H(7)NO, the two aromatic rings enclose a dihedral angle of 32.93 (12)°. The thiourea mol-ecule exists in its thione form in the solid state with typical C=S and C-N bond lengths. In the crystal, N-H⋯O hydrogen bonds exist between the thio-urea and carbonyl groups on the same and neighboring mol-ecules. In addition, each dimethyl-formamide solva...
