Crystal structures of dibromido{N-[(pyridin-2-yl-κN)methylidene]picolinohydrazide-κ2N′,O}cadmium methanol monosolvate and diiodido{N-[(pyridin-2-yl-κN)methylidene]picolinohydrazide-κ2N′,O}cadmium

The title compounds, [CdBr2(C12H10N4O)]·CH3OH, (I), and [CdI2(C12H10N4O)], (II), are cadmium bromide and cadmium iodide complexes of the ligand (E)-N′-(pyridin-2-ylmethylene)picolinohydrazide. Complex (I) crystallizes as the methanol monosolvate. In both compounds, the Cd2+ cation is ligated by one...
