Four Cu(I) complexes with 1-(2-hydroxyethyl)-5-mercapto-1H-tetrazole (Hhmt) as a ligand, [Cu(hmt)](n) (1), [Cu2Cl(hmt)](n) (2), [Cu4Br(hmt)(3)](n) (3), and [Cu4I(hmt)(3)](n) (4), have been synthesized. In 1-4, hmt adopts a mu(4) - eta(1) : eta(1) : eta S-2 coordinate mode to join the adjacent Cu(I) ions, which form different two-dimensional (2-D) structures. In 1, the neighboring four Cu(I) atoms are connected by mu(4)-hmt to form a 2-D structure. In 2, the Cu(I) ions are firstly connected with Cl ions to form a 1-D [Cu4Cl2] subunit chain, which then have been bridged by hmt to form a 2-D structure. However, the inorganic [Cu4Br] and [Cu4I] motifs are respectively connected by hmt to form 2-D structures in isostructural 3 and 4. In addition, the fluorescent properties and the thermal stability properties of 1-4 have been investigated. @@@ [GRAPHICS] @@@ .
