Abstract
- 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]
