Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Two new mononuclear coordination compounds, bis{4‐[(hydroxyimino)methyl]pyridinium} diaquabis(pyridine‐2, 5‐dicarboxylato‐κ²<italic>N</italic>, <italic>O</italic>²)zincate(II), (C₆H₇N₂O)₂[Zn(C₇H₃NO₄)₂(H₂O)₂], (1), and (pyridine‐2, 6‐dicarboxylato‐κ³<italic>O</italic>², <italic>N</italic>, <italic>O</italic>⁶)bis[<italic>N</italic>‐(pyridin‐4‐ylmethylidene‐κ<italic>N</italic>)hydroxylamine]zinc(II), [Zn(C₇H₃NO₄)(C₆H₆N₂O)₂], (2), have been synthesized and characterized by single‐crystal X‐ray diffractometry. The centrosymmetric Zn^II cation in (1) is octahedrally coordinated by two chelating pyridine‐2, 5‐dicarboxylate ligands and by two water molecules in a distorted octahedral geometry. In (2), the Zn^II cation is coordinated by a tridentate pyridine‐2, 6‐dicarboxylate dianion and by two <italic>N</italic>‐(pyridin‐4‐ylmethylidene)hydroxylamine molecules in a distorted <italic>C</italic>₂‐symmetric trigonal bipyramidal coordination geometry.</p> </abstract>
