Self-assembly of AgPF6 with pure bidentate ligand and mixed bidentate ligands produce desirable homoleptic and heteroleptic silver(I) coordination polymers, respectively, and their photoluminescent properties and thermal properties were characterized. •Homoleptic and heteroleptic Ag(I) coordination polymers have been easily synthesized.•Self-assembly produces tubular loop chain or 2-fold interwoven diamonoid structures.•Silver(I) coordination polymer shows a blue luminescence.•The calcination produces silver(0) microcrystalline morphology. Investigations into pure bidentate ligand vs mixed bidentate ligands on self-assembly of AgPF6 with the respective L1, L2, L3, L1/L2, L1/L3, and L2/L3 (L1=diethylbis(4-pyridyl)silane; L2=ethylmethylbis(4-pyridyl)silane; L3=cyclotetramethylenebis(4-pyridyl)silane) were carried out. The self-assembly reactions of AgPF6 with the respective ligand system produce desirable homoleptic or heteroleptic silver(I) coordination polymers. [Ag(L1)2](PF6) gives rise to a tubular loop chain whereas the other five products lead to a twofold interpenetration diamonoid structure. [Ag(L1)2](PF6) shows a strong blue luminescence at 453nm (λex=270nm), which is useful to recognize alcohols. All products were characterized by thermal analyses, and in particular, calcination of [Ag(L3)2](PF6)⋅CH3OH at 600°C finally produces silver(0) microcrystalline morphology.
