Crystal structure of (1,3-thia-zole-2-carboxyl-ato-?N)(1,3-thia-zole-2-carb-oxy-lic acid-?N)silver(I).

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 Ag^I 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?? inter-actions, leading to the formation of a three-dimensional supra-molecular architecture.
