Abstract

The linear two-coordinate silver (I) complex [Ag(C4H2NO2S)(C4H3NO2S)] or [Ag(2-Htza)(2-tza)] is reported (2-Htza = 1,3-thia-zole-2-carb-oxy-lic acid). The AgI ion is coordinated by two heterocyclic N atoms from two ligands in a linear configuration, forming a discrete coordination complex. There is an O-H⋯O hydrogen bond between 2-tza- and 2tzaH of adjacent complexes. The hydrogen atom is shared between the two oxygen atoms. This inter-action produces a hydrogen-bonded tape parallel to the [110] direction, which is augmented through inter-molecular C-H⋯O hydrogen-bonding inter-actions between the bound thia-zole groups. There is a further rather long Ag⋯O inter-action [2.8401 (13) Å, compared with a mean of 2.54 (11) Å for 23 structures in the CSD] that assembles these tapes into columns, between which there are C-H⋯π inter-actions, leading to the formation of a three-dimensional supra-molecular architecture.

Bartonellosis

Bartonellosis is an infection caused by bacteria in the genus Bartonella and can present as a variety of diseases depending on the organism involved. While asymptomatic infection has been reported, immunocompromised individuals are more susceptible to severe infection. Find the latest research on bartonellosis here.

Cat-scratch disease

Cat-scratch disease, a relatively common infectious disease, is caused by Bartonella henselae and characterized by a fever and regional lymphadenitis. Here is the latest research.
