(hfac = hexafluoroacetylacetonate) ( 3 ), one dinuclear complex [(CuLCl) 2 (μ-Cl) 2 ] · CH 3 OH ( 4 ), and two 1D chain species, [CuL 2 ] n (BF 4 ) 2n ( 5 ) and [CoL 2 ] n (ClO 4 ) 2n · 2 n CH 2 Cl 2 ( 6 ). The crystal structures of complexes 1 and 3–6 have been determined by X-ray crystallography. Short intermolecular S⋯S contacts between neighboring 1D arrays are observed in 5 and 6 , which lead to the formation
