Abstract
A new chromium(III) complex, [Cr(ox)(bdmpza)(H2O)], (ox = oxalate dianion and bdmpza = bis(3,5-dimethylpyrazol-1-yl)acetate, respectively), has been synthesized and characterized by X-ray crystallography. This compound crystallizes in the monoclinic space group P21/c, with a = 7.008(3) Å, b = 14.229(5) Å, c = 16.497(7) Å, β = 101.588(7)°, V = 1611.5(11) Å3, Z = 4. The chromium atom has a distorted octahedral environment with different coordination atoms. Bis(3,5-dimethylpyrazol-1-yl)acetate anion is a tridentate ligand, and the oxalate group acts as a chelating bidentate ligand. This compound also forms an infinite two-dimensional network through O–H ⋅ ⋅ ⋅ O hydrogen bonds. The lengths of the hydrogen bonds are 2.765(5) and 2.733(5) Å, respectively.
