Novel mononuclear, trinuclear, and hetero-trinuclear supermolecular complexes, [Co(phen){sub 2}(H{sub 2}O)(HTST)].2H{sub 2}O (1), [Co{sub 3}(phen){sub 6}(H{sub 2}O){sub 2}(TST){sub 2}].7H{sub 2}O (2), and [Co{sub 2}Cu(phen){sub 6}(H{sub 2}O){sub 2}(TST){sub 2}].10H{sub 2}O (3), have been synthesized by the reactions of a new tri-sulfonate ligand (2,4,6-tris(4-sulfophenylamino)-1,3,5-triazine, H{sub 3}TST) with the M{sup 2+} (M=Co, Cu) and the second ligand 1,10-phenanthroline (phen). Complex 1 contains a cis-Co(II)(phen){sub 2} building block and an HTST as monodentate ligand; complex 2 consists of two TST as bidentate ligands connecting one trans- and two cis-Co(II)(phen){sub 2} building blocks; complex 3 is formed by replacing the trans-Co(II)(phen){sub 2} in 2 with a trans-Cu(II)(phen){sub 2}, which is the first reported hetero-trinuclear supramolecular complex containing both the Co(II)(phen){sub 2} and Cu(II)(phen){sub 2} as building blocks. The study shows the flexible multifunctional self-assembly capability of the H{sub 3}TST ligands presenting in these supramolecular complexes through coordinative, H-bonding and even {pi}-{pi} stacking interactions. The photoluminescent optical properties of these complexes are also investigated and discussed as well as the second-order nonlinear optical properties of 1. - Graphical abstract: Novel mononuclear, trinuclear, and hetero-trinuclear supermolecular complexes, [Co(phen){sub 2}(H{sub 2}O)(HTST)].2H{sub 2}O (1), [Co{sub 3}(phen){sub 6}(H{sub 2}O){sub 2}(TST){sub 2}].7H{sub 2}O (2), and [Co{sub 2}Cu(phen){sub 6}(H{sub 2}O){sub 2}(TST){sub 2}].10H{sub 2}O (3), have been synthesized by the reactions of a new tri-sulfonate ligand (2,4,6-tris(4-sulfophenylamino)-1,3,5-triazine, H{sub 3}TST) with the M{sup 2+} (M=Co, Cu) and the second ligand 1,10-phenanthroline (phen).
