The terpyridine-inspired tridentate ligand, 2,6-bis-(5,6-dialkyl-1,2,4-triazin-3-yl)-pyridine (BTP), was synthesized and utilized to isolate five [MII(BTP)2]2+ (M = Fe and Co) transition metal complexes of various anions (BF4-, ClO4-, and NCS-). Notably, when metal-halide precursors are employed, 1:1 M:L products [Co2II(μ-X)2(BTP)2X2] (X = Cl or Br) are obtained, exhibiting μ-halide bridges. All complexes were structurally characterised through single crystal X-ray diffraction and their electrochemical and magnetic properties were investigated.
