The local atomic structure of habit-modifying transition metal cations within the crystal lattice of potassium dihydrogen phosphate (KDP) is investigated using X-ray absorption spectroscopy (XAS) and X-ray standing wave (XSW) spectroscopy, together with molecular modeling. XAS reveals the transition metal cations to be structurally incorporated into the crystal lattice as an ionic complex that ...

The Coumarine heterocyclic ring is common feature of various bioactive compounds such as calanolides, lipid-lowering agents. The Chemists all over the globe are motivated not only for the environmentally benign synthesis of new products but also to develop green synthesis for existing chemicals. Coumarins, the most important classes of fluorescent molecules constitute important structural featu...

Background: This experiment was conducted in two successive seasons on Picual olive trees which planted a private orchard located at El Khatatbah district belongs to Behera governorate, Egypt, and that order study the effect of potassium dihydrogen phosphate MKP (KH2PO4) addition fruit quality, yield its oil content, were sprayed concentrations (2 4%). The treatments applied three dates as foll...

A novel class of amide-functionalized pillar[5]arenes, that is, alkyl and aryl amide derivatives, has been synthesized. Highly selective binding of the dihydrogen phosphate anion over a range of anions by the new synthetic receptors is reported. First, the "binding strength-selectivity" relationship has been decided for the pillar[5]arene/anion systems.

Tautomeric switching is observed in a series of benzimidazole-based anion receptors upon addition of basic anions. An N-methylbenzimidazole based receptor selectively interacts with dihydrogen phosphate over a variety of other putative anionic guests via a combination of donated and accepted hydrogen bonds.
