Effects of different carboxylates on Ag(I) coordination compounds with pyrazinamide and pyrazinecarbonitrile with in situ reaction ligands

• Six silver(I) CCs of Pza/Pzn were synthesized and characterized.
• The structure of complex 1 exhibits a 2D silver sheet.
• The photoluminescence behaviors of the complexes were discussed.

Six coordination complexes were successfully synthesis through self-assembly of multiple components. Here upon ligands and different carboxylates variation, we reported on the assembly of six new organic–inorganic hybrid complexes with different silver nuclei. Four novel complexes based pza ligand and two new complexes based pzn ligand, namely {Ag6(pza)(pca)3(H2O)}n (1), {Ag2(pza)(pda)(H2O)}n (2), {Ag(pza)(pma)1/2⋅2H2O}n (3), {Ag2(pza)(pna)⋅3H2O}n (4), {Ag(pza)(pna)1/2}n (5), {Ag(pza)(pma)1/2⋅2H2O}n (6) have been synthesized successfully. A novel process for the synthesis of complexes 5 and 6 was pzn ligand with in situ reaction in solution to be pza in the formation of crystals. They were fully characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. Complexes 1–3 and 5 show 2D layer structures and complexes 4 and 6 are 1D chain structures which is depicted in Scheme 1. A noticeable structure feature in complex 1 is that the arrangement of Ag(I) ions is a 2D sheet. And the pca ligands anchor on the 2D silver net to form 2D layer structure. In complex 3 is 1D infinite chain structure which contains 1D silver chain.
