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

In the presence of aromatic carboxylic acids, three new d(10) transition metal coordination polymers, [Ag(PAHT)](n) (1), [Ag2(HCA)](n) (2) and [Cu-6(CA)(2)(H2O)](n) (3) (HPAHT=2-pheny1-4-amino-6-hydroxy-1,3,5-triazine, H(3)CA= 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 hg LiCe type topology, which contains righthanded 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)center dot center dot center dot 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 CA(3-) with a rare uninodal 10-connected bct topology (3(12).4(28).5(5)). The photoluminescent properties of three compounds have also been measured. (C) 2013 Elsevier Inc. All rights reserved.
