Abstract

•New complexes with the same starting materials were successfully achieved.•Solvent and/or counter anion play a key role for complex formation.•Semi-rigid bi-pyrimidinyl sulfide takes an interesting unvaried configuration.

The silver(I) complexes {[Ag(DprS)(CH3CN)](ClO4)}∞ (1) with a ladder-like motif and [Ag2(DprS)(CF3CO2)2]∞ (2) with a two-dimensional net were respectively obtained through solvent medium tuning effect (DprS = di-pyrimidinyl sulfide), while complex {[Ag3(DprS)4(C2F5CO2)](CF3SO3)2·H2O}∞ (3) was achieved as a tape-like coordination motif in the presence of mixed counter anions. In 1–3, even in the crystalline state of the neat form DprS, each DprS molecule takes an unvaried non-planar configuration stabilized by intramolecular Npyrimidinyl⋯Cpyrimidinyl contact. Complexes 1–3 and the DprS ligand were fully characterized through single-crystal X-ray diffraction, elemental analysis, FT-IR spectroscopy and luminescent emission measurement. The effect of the choice of solvent and anion on the structure is discussed.

Graphical abstractThree new Ag(I) complexes of di-pyrimidinyl sulfide with different topological coordination motifs were readily achieved through anion and/or solvent medium tuning effect, wherein the ligands take an unvaried ligation mode with a non-planar configuration.Figure optionsDownload full-size imageDownload as PowerPoint slide
