Six coordination compounds of Ag(I) and 2,4-diamino-6-[2-(2-methyl-1-imidazolyl)ethyl]-1,3,5-triazine (L, Ag:L = 1:2) with different anions and solvents, namely, [Ag(L) 2 ]∙(NO 3 )∙4(H 2 O) ( 1 ), [ Ag ( L ) 2 ] · 1 / 2 ( nds ) · ( MeOH ) · ( H 2 O ) ( 2 , H 2 nds = 1,5-naphthalenedisulfonic acid), [ Ag ( L ) 2 ] · 1 / 2 ( nds ) · ( MeOH ) · 5 / 2 ( H 2 O ) ( 3 ), [ Ag ( L ) 2 ] · 1 / 2 ( nds ) · ( CH 3 CN ) ( 4 ), [Ag(L) 2 ]∙(ClO 4 )∙(MeOH)∙(H 2 O) ( 5 ), and [Ag(L) 2 ]∙(ClO 4 )∙2(H 2 O) ( 6 ), have been synthesized and characterized by elemental analysis, IR, PXRD and X-ray single-crystal diffraction. In these compounds, each Ag(I) ion is ligated by two imidazole nitrogens to form a Ag(L) 2 unit. The anions and solvents determine hydrogen-bonding between the DAT groups links the Ag(L) 2 units whether to form chains in 1 and 2 or layers in 3 – 6 . In addition, thermogravimetric analysis (TGA) and luminescent properties of these compounds were also investigated. [ABSTRACT FROM AUTHOR]

Three mix-ligand Ag(I) coordination compounds, namely, {[Ag 10 (tpyz) 5 (L1) 5 (H 2 O) 2 ].(H 2 O) 4 } n ( 1 , tpyz = 2,3,4,5-tetramethylpyrazine, H 2 L1 = phthalic acid), [Ag 4 (tpyz) 2 (L2) 2 (H 2 O)].(H 2 O) 5 } n ( 2 , H 2 L2 = isophthalic acid) {[Ag 2 (tpyz) 2 (L3) (H 2 O) 4 ].(H 2 O) 8 } n ( 3 , H 2 L3 = terephthalic acid), have been synthesized and characterized by elemental analysis, IR, PXRD and X-ray single-crystal diffraction. 1 exhibits a 2D layer which can be simplified as a (4,4) net. 2 is a 3D network which can be simplified as a (3,3)-connected 2-nodal net with a point symbol of {10 2 .12}{10 2 }. 3 consists of linear [Ag(tpyz) (H 2 O) 2 ] n chain. Of particular interest, discrete hexamer water clusters were observed in 1 and 2 , while a 2D L10(6) water layer exists in 3 . The results suggest that the benzene dicarboxylates play pivotal roles in the formation of the different host architectures as well as different water aggregations. Moreover, thermogravimetric analysis (TGA) and emissive behaviors of these compounds were investigated. [ABSTRACT FROM AUTHOR]
