KV,Ca beta subunit dramatically increases the apparent calcium sensitivity of the alpha subunit of MaxiK channels when probed in the micromolar [Ca2+]i range. Analysis in a wide range of [Ca2+]i revealed that this functional coupling is exquisitely modulated by [Ca2+]i. Ca2+ ions switch MaxiK alpha+beta complex into a functionally coupled state at(More)
The title compound, {[Pr(C(2)H(6)OS)(8)](2)[Mo(6)Ag(6)S(24)]}(n), contains polymeric Mo(6)S(24)Ag(6) (2-) anions and [Pr(Me(2)SO)(8)](3+) cations, forming a one-dimensional polymeric Mo/S/Ag cluster. The anion assumes the conformation of a zigzag chain. The trivalent cations are arrayed amongst the anionic chains and are well separated from each other. Each(More)
The title compound, [Cu(6)V(2)O(2)S(6)(C(6)H(8)N(2))(6)], is constructed from six CuS(3)N and two VOS(3) distorted tetra-hedra, forming an octa-nuclear V/S/Cu cluster with C(i) symmetry. The geometry around the V atoms is slightly distorted tetra-hedral, while there are large distortions from ideal tetra-hedral geometry for the Cu atoms. Adjacent(More)
In the title polymeric complex, [HgBr(2)(C(10)H(14)N(2))](n), each nicotine mol-ecule is bonded to two adjacent Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming zigzag chains along [010]. The coordination around mercury is completed by two bromido ligands resulting in a distorted tetra-hedral arrangement.
The title polymeric complex, [HgI(2)(C(10)H(14)N(2))](n), was prepared from a solution of nicotine, mercury(II) iodide and 4-cyano-pyridine in dimethyl-formamide. Each nicotine mol-ecule is bonded to two Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming infinite zigzag polymeric chains. The coordin-ation around(More)
The asymmetric unit of the title compound, [Cd(C(10)H(8)N(2))(3)](ClO(4))(2)·0.5H(2)O, consists of one complex [Cd(bpy)(3)](2+) cation (bpy = 2,2'-bipyridine), two perchlorate anions and one water molecule with half-occupancy. The central cadmium(II) ion is bound to six N atoms from three bpy ligands in a distorted octa-hedral coordination, with Cd-N bond(More)
The reaction of mercury(II) chloride with 5-amino-2,4,6-triiodo-isophthalic acid in pyridine solution leads to the formation of the title compound, [Hg(C(8)H(2)I(3)NO(4))(C(5)H(5)N)(2)](n). The structure contains a four-coordinate Hg(2+) ion in a distorted tetra-hedral geometry, which lies on a crystallographic twofold axis. The Hg(2+) ion is bonded to two(More)
