Abstract
A series of transition metal complexes [Mn(HL)2](ClO4)2 · 0.25H2O (1), [Fe(L)2](ClO4) · H2O (2), [Fe(L)2](BF4) · C7H8N4 (3), [Co(HL)(L)](ClO4) · H2O (4), [Co(HL)(L)](ClO4) · 1.5C2H5OH (5), and [Ni(L)2] · H2O (6), where HL=2‐acetylpyridine thiosemicarbazone, C7H8N4=bis(pyrazolyl)methane, have been synthesized and their structures were determined. All the metal centers are six‐coordinate with 4 nitrogen atoms and 2 sulfur atoms from 2 ligands. Complexes 1–3 and 5 are mononuclear complexes while complexes 4 and 6 contain hydrogen bonds that separately connect the molecule units into multi‐dimensional structure and aggregation. These complexes are potential molecular bricks of the multi‐dimensional or heterometallic complexes containing sulfur atoms.
