Abstract
- Reaction of isoquinoline (iQuin) with cobalt(II) and nickel(II) chloride and bromide produced a family of neutral coordination complexes: (iQuin)<subscript>2</subscript>CoX<subscript>2</subscript> [X = Cl (1), Br (2)], (iQuin)<subscript>4</subscript>CoX<subscript>2</subscript> (X = Cl (3), X = Br (4)], (iQuin)<subscript>4</subscript>NiX<subscript>2</subscript> [X = Cl, (5), X = Br, (6)], and (iQuin)<subscript>2</subscript>NiBr<subscript>2</subscript>(CH<subscript>3</subscript>CN)<subscript>2</subscript> (7). The crystal structures of 1–5 and 7 are reported. The majority of the compounds crystallize with some of the iQuin ligands undergoing a ∼2-fold rotational disorder, likely caused by the nearly equivalent space occupied by the two positions. The disorder is temperature independent and ∼50:50 in all cases but one. Magnetic measurements for all seven compounds indicate that their behavior is dominated by single-ion anisotropy effects with indications of antiferromagnetic exchange also present in 1 and 2.
