Dinuclear ruthenium nitrido complexes supported by the Kläui's tripodal ligand [CpCo{P(O)(OEt)(2)}(3)](-) (L(OEt)(-)) have been synthesized starting from the ruthenium(VI) nitrido precursor [L(OEt)Ru(VI)(N)Cl(2)] (1). Heating a solution of 1 in CCl(4) at reflux, followed by recrystallization from hexane under nitrogen, afforded the mixed-valence ruthenium(V)-ruthenium(IV) μ-nitrido complex [L(O...

In the title compound, [Cd(2)Cl(6)(C(4)H(10)NO)(2)](n), the coordination geometry of each Cd(II) ion is distorted octa-hedral, but with quite different coordination environments. One Cd(II) atom is coordinated by four Cl atoms and two O atoms from two morpholinium ligands, while the other is coordinated by six Cl atoms. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride br...

In the title salt, [ZnCl(C(6)H(7)N(3))(2)]Cl·2H(2)O, the pyridine-2-carboximidamide ligands chelate to the Zn(II) atom, which is also coordinated by a Cl atom. The Zn(II) atom shows a trigonal-bipyramidal coordination, with the pyridyl N atoms occupying the axial positions. The cation, anion and water mol-ecules are linked by N-H⋯Cl, N-H⋯O, O-H⋯Cl and O-H⋯O hydrogen bonds into a three-dimension...

The centrosymmetric dinuclear Cu(II) complex, [Cu(2)Cl(4)(C(24)H(21)N(5)O(4))(2)], was synthesized by the reaction of CuCl(2)·2H(2)O with the tripodal ligand 2,2'-[3-(1H-imid-azol-4-ylmeth-yl)-3-aza-pentane-1,5-di-yl]diphthalimide (L). Each of the Cu(II) ions is coordinated by two N atoms from the ligand, two bridging Cl atoms and one terminal Cl atom. The Cu(II) coordination can be best be des...

Cu(II)Cl complexes can undergo stepwise electrochemical reduction to Cu(I)Cl and then to Cu. In this paper, the Nernst equation is used to simultaneously calculate the temperature-dependent stability constants of both mononuclear Cu(II)Cl and Cu(I)Cl complexes for the first time. First, voltammograms were recorded at a Pt ultramicroelectrode (UME) with a variable of free chloride concentration ...

Two ruthenium carbonyl complexes with the 4'-chloro-2,2':6',2''-terpyridine ligand (tpy-Cl, C15H10ClN3), i.e. [RuCl(tpy-Cl)(CO)2][RuCl3(CO)3] (I) [systematic name: cis-di-carbonyl-chlorido(4'-chloro-2,2':6',2''-terpyridine-κ3N)ruthenium(II) fac-tricarbonyltri-chlorido-ruthenate(II)], and [RuCl2(tpy-Cl)(CO)2] (II) [cis-dicarbonyl-trans-di-chlorido(4'-chloro-2,2':6',2''-terpyridine-κ2N1,N1')ruthe...

Pendrin (Slc26a4) localizes to type B and non-A, non-B intercalated cells in the distal convoluted tubule, the connecting tubule, and the cortical collecting duct (CCD), where it mediates apical Cl(-)/HCO(3)(-) exchange. The purpose of this study was to determine whether angiotensin II increases transepithelial net chloride transport, J(Cl), in mouse CCD through a pendrin-dependent mechanism. J...

Cationic and anionic species of heavier low-valent group 14 elements are intriguing targets in main group chemistry due to their synthetic potential and industrial applications. In the present study, we describe the synthesis of cationic (MCl(+)) and anionic (MCl(3)(-)) species of heavier low-valent group 14 elements of germanium(II) and tin(II) by using the substituted Schiff base 2,6-diacetyl...

A recently cloned isoform of cGMP-dependent protein kinase (cGK), designated type II, was implicated as the mediator of cGMP-provoked intestinal Cl- secretion based on its localization in the apical membrane of enterocytes and on its capacity to activate cystic fibrosis transmembrane conductance regulator (CFTR) Cl- channels. In contrast, the soluble type I cGK was unable to activate CFTR in in...
