Source of material
All materials were obtained from commercial sources and used without further purification. The title compound was prepared under mild hydrothermal condition by the following procedure: a mixture of pyrazolo [1,5-a]pyrimidine-3-carboxylic acid (32.6 mg, 0.2 mmol), Ni(CH3COO)2·4H2O (49.8 mg, 0.2 mmol) and 10 mL deionized water was sealed in a 25 mL Teflon-lined stainless steel vessel and heated at 353 K for four days under autogenous pressure. Then the reaction was stopped and cooled to room temperature and filtered. Green block crystals of the title complex were obtained.
Experimental details
Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.
Comment
The syntheses and characterization of nickel(II) complexes constructed from organic ligands are receiving growing attention due to their potential applications [5], [6], [7]. The organic ligands can be aromatic carboxylates, aliphatic carboxylates, N-heterocyclic carboxylates or other species. The N-heterocyclic pyrazolo[1,5-a]pyrimidine-3-carboxylic acid could be deprotonated by hydrothermal treatment, and provides oxygen and nitrogen atoms to coordinate with central metal ions [8, 9]. Herein, we describe the synthesis and structural characterization of one mononuclear nickel(II) complex based on pyrazolo[1,5-a]pyrimidine-3-carboxylate.
The title complex, C14H16N6O8Ni, was synthesized using Ni(CH3COO)2·4H2O and pyrazolo[1,5-a]pyrimidine-3-carboxylic acid under hydrothermal condition. Single crystal X-ray structural analysis shows that the complex crystallizes in the monoclinic space group P21/n. The asymmetric unit contains half a Ni2+ ion, one deprotonated pyrazolo[1,5-a]pyrimidine-3-carboxylate anion, one coordinated water molecule and one uncoordinated water molecule. The Ni(II) ion is six-coordinated with one carboxylate O atoms, two pyridine N atoms from two pyrazolo[1,5-a]pyrimidine-3-carboxylate ligands, and two O atoms from two coordinated water molecules, generating a distorted octahedral coordination geometry. In the title complex, the Ni–O distances are 2.0569(13) Å and 2.0719(14) Å. The Ni–N distance is 2.0990(15) Å. The Ni–O/N distances are consistent with other reported structures [10, 11]. The complex is connected to each other through O–H⋯O and O–H⋯N hydrogen bonds between the coordinated water molecules and N atoms of the pyrazolo[1,5-a]pyrimidine-3-carboxylate ligands to form a 3D structure.
