One of the three pyrazolyl groups of the scorpionato ligand occurs in the protonated form in the bright orange Cu complex [(Tp Cy )HCuCl 2 ] ( 1 ) and forms a hydrogen bond with a Cu‐bound Cl atom. In the reaction of [Tp Cy Tl] with CuCl 2 ṁ2H 2 O. 1 is formed rather than the expected complex [Tp Cy MCl] (Tp Cy = [HB(cyclohexylpyrazolyl) 3 ], R = Cy = cyclohexyl).
