Crystal structure of (1,3-thia­zole-2-carboxyl­ato-κN)(1,3-thia­zole-2-carb­oxy­lic acid-κN)silver(I)

The linear two-coordinate silver (I) complex [Ag(C(4)H(2)NO(2)S)(C(4)H(3)NO(2)S)] or [Ag(2-Htza)(2-tza)] is reported (2-Htza = 1,3-thia­zole-2-carb­oxy­lic 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 inter­action produces a hydrogen-bonded tape parallel to the [110] direction, which is augmented through inter­molecular C—H⋯O hydrogen-bonding inter­actions between the bound thia­zole groups. There is a further rather long Ag⋯O inter­action [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 inter­actions, leading to the formation of a three-dimensional supra­molecular architecture.
