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)
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 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)
In the title compound, [N(C4H9)4][Sn(C4H9)Cl4], the Sn(IV) atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetra-butyl-ammonium cation are partially disordered, each with refined site(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 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.
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)
The asymmetric unit of the title organotin salt, (C(8)H(20)N)[Sn(C(6)H(5))(3)(CH(4)O(3)P)(2)], contains two dibutyl-ammonium cations and two stannate(IV) anions consisting each of two monodentately bonding methyl hydrogenphosphate groups attached to an Sn(C(6)H(5)) unit. The overall coordination environment of the two Sn(IV) atoms is trigonal-bipyramidal(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)
