The title compound, (C(8)H(20)N)[Tb(C(5)HF(6)O(2))(4)], is a tetrakis β-diketonate complex of hexa-fluoro-acetyl-acetone with terbium(III), and tetra-ethyl-ammonium as the counter-ion. This compound shows typical green terbium(III) luminescence upon excitation at about 335 nm. The coordination geometry around the Tb(III) atom is a slightly distorted square anti-prism. One hexa-fluoro-acetyl-ace...

In the title compound, [Tb(CH(3)CN)(C(23)H(26)O(8))(H(2)O)(3)](ClO(4))(3), the Tb(3+) atom is eight-coordinated by one N atom of an acetonitrile molecule, three water O atoms and four ligand O atoms. The Tb(3+) atom is located on one side of the macrocycle and the carbonyl oxygen coordinated to the terbium [Tb1-O1= 2.210 (3) Å] is bent out of the xanthone plane by 0.514 (3) Å. The geometry arou...

A novel luminescent chemosensor for detecting Hg(2+) with high selectivity, based on a pendant benzo crown ether terbium complex, has been designed and prepared.

Objective: Pharmacological effects of carvacrol such as its anti-inflammatory activities have been shows. In this study the effects of carvacrol on serum levels of total protein (TP), phospholipase A2 (PLA2) and histamine in sensitized guinea pigs was evaluated. Materials and Methods: Sensitized guinea pigs were given drinking water alone (group S), drinking water containing three concentration...

objective: inflammation is one of the major components of asthma. our aim was to evaluate the effects of c. sativus extract on total and differential white blood cells (wbc) count in lung lavage fluid (llf) of ovalbumin-sensitized rats. materials and methods: forty rats were divided into five groups (n = 8 for each group) as control (c), sensitized with injection and inhalation of ovalbumin (oa...
