The new complex of [H2en][Cu(pydc)2].2H2O (1) (where H2en and pydc are ethylenediammonium and 2,6-pyridinedicarboxylate, respectively) was synthesized by the reaction of a mixture of ethylenediamine (en) and 2,6-pyridinedicarboxylic acid (H2pydc) in a mixture of CH3OH/H2O as solvent. This complex was fully characterized by elemental analysis, IR, UV–Vis spectroscopy as well as single-crystal X-ray diffraction method. The crystallographic analysis revealed that the complex of 1 consists of discrete [Cu(pydc)2]2- anion, two bis(protonated) ethylenediamine cation and two crystal water molecules. In the anionic part of this complex, the copper(II) cation is coordinated by two tridentate pydc anionic ligands through the two oxygen atoms of two carboxylate groups and one nitrogen atom of pyridine ring. Also, in this complex, intermolecular C-H…O, N-H…O and O-H…O hydrogen bonds and the strong π…π interactions between the pyridine rings are effective on the stabilization of the crystal packing.

Nature has been a wellspring of therapeutic operators for a huge number of years and an exceptional number of present day drugs have been secluded from common sources. Higher plants, as wellsprings of restorative mixes, have kept on assuming a prevailing part in the support of human wellbeing since old circumstances. More than half of all cutting edge clinical medications are of characteristic item starting point and assume a critical part in tranquilize advancement programs in the pharmaceutical business. Blepharis is an Afro-asiatic class including 129 species, having a place with the family Acanthaceae, broadly circulated in bone-dry and semi-dry natural surroundings. A portion of the animal varieties incorporate B. attenuata Napper, Blepharis edulis, B. sindica, and B. maderaspatensis. Blepharis maderaspatensis (L.) Heyne ex Roth is utilized for treatment of various illnesses like dysuria, cerebral pain, and maladies of sensory system, diuretic and love potion. These plants show an extensive variety of pharmacological exercises including cell reinforcement, mitigating, hostile to joint, antimicrobial, antifungal, against ulcer and cytotoxic exercises. Some settled pharmacological exercises of these plants have been talked about in this article. Wide varieties of the plants and their dynamic standards have been assessed for pharmacological properties. The plant species being generally conveyed can be utilized as another option to the customary medications. Subsequently, there is a need to know the plausibility of utilizing removes and bioactive mixes got from such plants for the control of perpetual infections as asserted by customary healers.

As part of the development of equipment and innovative technology for the process flow-sheet, a study on the selection of good resin for uranium uptake is ongoing. Both static and dynamic column equilibrium testing upon synthetic and Gattar pregnant leach solutions (PLS) were carried out to estimate the change of total capacity and breakthrough capacity of the commercial macroporous anion exchange resin (D201). Applying the static and dynamic methods upon synthetic uranium sulphate solution, the maximum adsorption capacity of uranium (VI) upon D201 resin was evaluated to be 105 and 101.2mgU/g respectively. The macroporous D201 resin has been found to agree with the Langmuir isotherm. Finally, the optimized factors have been carried out for uranium recovery from Gattar pregnant leach solution, under the optimized working conditions, about 93 and 90 % of the resin theoretical capacity was realized using both static and dynamic techniques respectively.
