Bis(triphenylphosphine)silver(i) perrhenate, a cyclic dimer.
The 1 : 4 and 1 : 2 complexes of silver perrhenate and triphenylphosphine, [(Ph3P)4Ag](+) ReO4(-) and [(Ph3P)2AgReO4]2, have been prepared and their structures determined in the solid state by X-ray diffraction. The former is composed of independent ions, while in the latter the ions are aggregated into cyclic dimers. The silver centers are tetracoordinated including contact with two bridging p...
متن کاملBis[glycinium(0.5+)] perrhenate
All the residues of the title compound, (C(2)H(5.5)NO(2))(2)[ReO(4)], are located in general crystallographic positions. The glycine mol-ecules have usual conformations [Rodrigues Matos Beja et al. (2006 ▶). Acta Cryst. C62, o71-o72] with the H atom of the carboxylate group half-occupied, thus bearing a formal half-positive charge per molecule. The perrhenate anion has nearly ideal tetra-hedral...
متن کاملA new cyclic RGD peptide dimer for integrin αvβ3 imaging.
OBJECTIVE To design a new Arg-Gly-Asp (RGD) peptide that can specifically bind integrin αvβ3 and evaluate the possibility of using 131I-labeled peptide for imaging αvβ3-positive tumors. MATERIALS AND METHODS The structure of the RGD monomer was selected using V-life software. Based on the RGD monomer, a dimer of cyclic RGD [c(RGD)2] linked by Tyr-(D)Ser-Lys-(D)Ser-Ser with a Gly-Gly-(D)Ala-Gl...
متن کامل2-Amino-3-nitropyridinium perrhenate
In the title mol-ecular salt, (C(5)H(6)N(3)O(2))[ReO(4)], the cations and tetrahedral anions are linked by trifurcated N-H⋯(O,O,O) and bifurcated N-H⋯(O,O) hydrogen bonds, as well as weak C-H⋯O inter-actions. This results in alternating corrugated inorganic and organic layers in the crystal.
متن کاملMacrocyclic receptor for pertechnetate and perrhenate anions.
The design and synthesis of a neutral macrocyclic host that is capable of perrhenate and pertechnetate recognition is described. The anion affinities and underlying coordination modes were estimated by several experimental and theoretical methods including a new technique--reverse (99)Tc NMR titration.
