Syntheses, structures and photoluminescent properties of three d10 coordination architectures based on in-situ 1,3,5-triazine derivatives

• The compound 1 exhibits a new 3D network with two kinds of single helical chains.
• New 3D d10 transition metal coordination polymers.
• The photoluminescent properties have been measured.

In the presence of aromatic carboxylic acids, three new d10 transition metal coordination polymers, [Ag(PAHT)]n(1), [Ag2(HCA)]n(2) and [Cu6(CA)2(H2O)]n(3) (HPAHT=2-phenyl-4-amino-6-hydroxy-1,3,5-triazine, H3CA=cyanuric acid) have been synthesized based on in-situ 1,3,5-triazine derivatives resulting from 2,4-diamino-6-phenyl-1,3,5-triazine, 2-chloro-4,6-diamino-1,3,5-triazine and melamine under hydrothermal conditions. Complexes 1–3 have been characterized by single-crystal X-ray diffraction, IR spectra, elemental analysis and thermogravimetric analysis (TGA). The compound 1 exhibits a uninodal three-connected 3D network with a rare lig LiGe type topology, which contains right-handed and left-handed [Ag(PAHT)]n helical chains. For compound 2, the 3D network is comprised of 2D sheet by strongly Ag–O and weakly Ag(I)…Ag(I) interactions. In compound 3, it is infrequently observed that dodecanuclear copper(I) units as secondary building units (SBUs) construct 3D network by the ligands CA3− with a rare uninodal 10-connected bct topology (312.428.55). The photoluminescent properties of three compounds have also been measured.

Three d10 transition metal coordination polymers 1–3 have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, IR spectra, elemental analysis, photoluminescent spectra and thermogravimetric analysis (TGA).Figure optionsDownload as PowerPoint slide
