In the title compounds, bis[2-(3-nitrophenylnitrilomethylidyne)phenolato-N,O]zinc(II), [Zn(C₁₃H₉N₂O₃)2], and bis[2-(3-methoxyphenylnitrilomethylidyne)phenolato-N,O]zinc(II), [Zn(C₁₄H₁₂NO₂)₂], the tricilinic unit cell contains two inversion-related molecules. In both compounds, the Zn atom is in a slightly distorted tetrahedral coordination involving O and N atoms of two bidentate ligands. The dihedral angle defined by the two chelate rings is 98.09 (4)° for the methoxyphenyl complex and 98.05 (7)° for the nitrophenyl complex. The molecules are crosslinked via intermolecular hydrogen bonds.
