Six complexes based on a flexible tripodal ligand H{sub 3}TTTA (2,2',2''-[1,3,5-triazine-2,4,6-triyltris(thio)]tris-acetic acid) have been hydrothermally synthesized and structurally characterized. X-ray single-crystal diffractions reveal that they have rich structural chemistry: mononuclear, [Zn(HTTTA)(2,2'-bpy)(H{sub 2}O){sub 3}]{sub n} (1); dimeric metallamacrocycle, [Zn(HTTTA)(2,2'-bipy)(H{sub 2}O)]{sub n} (2) and [Cd(HTTTA)(2,2'-bipy)(H{sub 2}O).H{sub 2}O]{sub n} (3); two-dimensional networks with binodal (3,6)-connected CdI{sub 2} topology based on linear trinuclear M{sub 3}({mu}{sup 2}-CO{sup 2}){sub 4}({mu}{sub 2}-CO{sub 2}){sub 2} SBUs (Secondary Building Units), [M{sub 3}(TTTA){sub 2}(2,2'-bipy){sub 2}(H{sub 2}O){sub m}.nH{sub 2}O]{sub n} (M=Zn.4, m=0, n=4; Cd.5 and Mn.6, m=2; n=2). The value of pH and the metal ions has large influences on the resulting structures. The flexible tricarboxylic acid exhibits four coordination modes from monodentate to {mu}{sup 6}-bridge. Fluorescence and magnetic properties of the complexes have also been investigated in details. - Graphical abstract: Six complexes based on a flexible tricarboxylate ligand exhibit rich structural chemistry from mononuclear to 2D (3,6)-connected networks. PH and metal ions have large influences on the resulting structures. Highlights: > Six complexes based on a flexible multicarboxylate ligand have been reported. > They exhibit diverse structures from mono- and binuclear molecules to 2-D layers. > pH and metal ions have large influences on the final products.
