Complexes between hepatitis B surface antigen (HBsAg) and immunoglobulin M (IgM) have been detected in acute type B hepatitis. Sequential serum testing for the presence of these complexes has been shown to be the best method for predicting disease chronicity. The presence of HBsAg/IgM complexes was investigated using an enzyme-linked immunosorbent assay(More)
The title compound, [(CH(3))(3)NH](2)[Sn(C(6)H(5))(2)Cl(4)], consists of [(CH(3))(3)NH](+) cations and [SnPh(2)Cl(4)](2-) anions in which the Sn atom, located on a centre of inversion, is bonded to four Cl atoms and two phenyl rings, giving an octa-hedral geometry with the phenyl rings in trans positions. In the crystal, the cations and the anions are(More)
In the structure of the title monomeric coordination salt, (C(3)H(10)N)[Sn(C(6)H(5))(3)Cl(2)], the Sn(IV) atom is five coordinate, with the SnC(3)Cl(2) entity in a trans trigonal-bipyramidal arrangement and the chlorine atoms in apical positions. In the crystal, the cations and anions are connected by N-H⋯Cl hydrogen bonds.
Crystals of the title salt, C(21)H(20)OP(+)·NO(3) (-), are composed of acetonyltriphenyl-phospho-nium cations and nitrate anions that mainly inter-act through electrostatic forces. The P atom in the cation has a slightly distorted tetra-hedral environment, with C-P-C angles ranging from 104.79 (7) to 112.59 (6)°. The sum of O-N-O angles of the nitrate anion(More)
In the title salt, [(C(6)H(11))(2)NH(2)](+)·[C(6)H(5)PO(2)(OH)](-), the anion is monodeprotonated and acts as both a hydrogen-bond donor and acceptor. The anions are linked by pairs of O-H⋯O inter-actions, forming inversion dimers with R(2) (2)(8) ring motifs. These dimers are bridged by two dicyclo-hexyl-aminium cations via pairs of N-H⋯O hydrogen bonds,(More)
In the structure of the title coordination polymer, {(C16H36N)[Sn2(CH3)6Cl(SO4)]} n , the two independent Sn(IV) atoms are coordinated in a trigonal-bipyramidal manner by three methyl groups in the equatorial plane and in the axial positions by either two O atoms of bridging SO4 (2-) anions or by a Cl atom and one O atom of a bridging SO4 (2-) anion,(More)
Regular crystals of the title compound, (C(2)H(8)N)(2)[Sn(CH(3))(2)Cl(4)], were obtained by reacting SnMe(2)Cl(2) with (CH(3))(2)NH·HCl in ethanol in a 1:1 ratio. The Sn atom lies on a center of symmetry and is six-coordinated. It has a distorted octahedral SnC(2)Cl(4) environment with the Cl atoms in cis positions. The Cl atoms are connected to(More)
In the structure of the title coordination polymer, {(C(8)H(20)N)[Sn(3)(CH(3))(9)(SO(4))(2)]}(n), each of the three Sn(IV) atoms is coordinated in a trigonal-bipyramidal manner by three methyl groups in the equatorial plane and by two O atoms of SO(4) (2-) anions in the axial positions. The μ(3)-bridging mode of the sulfate anions leads to the formation of(More)
In the structure of the title coordination polymer, [Sn(C(6)H(5))(3)(C(6)H(6)O(2)P)](n) or [PhP(H)O(2)Sn(IV)(Ph)(3)](n), the Sn(IV) atom is five-coordinate, with the SnC(3)O(2) framework in a trans trigonal-bipyramidal arrangement having the PhP(H)O(2) (-) anions in apical positions. In the crystal, neighbouring polymer chains are linked via C-H⋯π(More)
