Hexacarbonyltechnetium(I) perchlorate

چکیده
The title compound, [Tc(CO)(6)]ClO(4), was synthesized by the reaction of [TcCl(CO)(5)] with AgClO(4), followed by acidification with HClO(4) under a CO atmosphere. The [Tc(CO)(6)](+) cation has close to idealized octa-hedral geometry, with the bond angles between cis-CO groups close to 90° and the Tc-C bond lengths in the range 2.025 (3)-2.029 (3)Å. The perchlorate anion is disordered over two crystallographically equivalent half-occupied positions. The Tc atom in the [Tc(CO)(6)](+) cation is located on an inversion centre.

متن کاملReview of the “ Public Health Goal for Perchlorate in Drinking Water ”
I have reviewed the draft document dated January 11, 2011 as well as the online posted comments of external interested parties. I am an environmental epidemiologist with a primary research area outside of perchlorate and related health effects, but have done some work with perchlorate. I am pleased to have been given the opportunity to review this document and to offer some technical suggestion...
متن کاملComment on "Intake of iodine and perchlorate and excretion in human milk".
Perchlorate, thiocyanate, and iodine excretion in urine and milk of 13 breastfeeding women was investigated and the results were interpreted by a model of parallel/competitive transport of these species bythe sodium iodide symporter. For each species i, we assumed physiological homeostasis, where i(T,in) equals the corresponding total excretion in urine and milk (i(e,u) + i(e,m)). The fraction ...

In the title compound, {[Ag(3)(C(10)H(8)N(2))(3)](ClO(4))(3)·2H(2)O}(n), one of the Ag(I) ions, one of the 4,4'-bipyridine (bipy) ligands and one of the perchlorate anions are each situated on a twofold rotation axis. Each Ag(I) ion is coordinated by two N atoms from two bridging bipy ligands, forming chains along [101]. π-π inter-actions between the pyridine rings [centroid-centroid distances ...
متن کاملcatena-Poly[[silver(I)-μ-4-aminopyridine] perchlorate]: a 1-D staircase coordination polymer
Reaction of 4-amino-pyridine with silver(I) perchlorate leads to a one-dimensional coordination polymer, {[Ag(C(5)H(6)N(2))]ClO(4)}(n), in which the amino-pyridine binds through both N atoms. The perchlorate anion is hydrogen bonded to the amino H atoms and inter-acts weakly with the silver(I) atoms (Ag-O > 2.70 Å), both located on inversion centres, and some aromatic H atoms (O-H > 2.55 ÅA), t...
