Source of material

The title compound has been synthesized by following method: 0.0498 g 6-phenylpyridine-2-carboxylic acid (0.25 mmol), 0.0208 g 1H-pyrazol-3-ylamine (0.25 mmol), 0.020 g NaOH (0.5 mmol), and 0.0623 g Co(CH3COO)2·4H2O (0.25 mmol) were placed in a 100 mL flask containing 20 mL of an ethanol-water solution (v:v = 1:1) under stirring. Then the mixture was gradually heated up to 75 °C and maintained at this temperature for a further 5 h under constant stirring. The reactants were cooled to room temperature and filtered, and the filtrate was placed into a small conical flask to evaporate slowly. The yellow crystals of the title compound were received from the above solution in 20 days.

Experimental details

The hydrogen atoms were positioned geometrically (C–H = 0.93 Å, N–H = 0.86–0.89 Å and O–H = 0.85 Å). Their U iso values were set to 1.2U eq or 1.5U eq of the parent atoms.

Comment

The studying on the structure and properties of metal complexes has been one of the scientific hotspots [5], [6], [7], [8], [9]. 6-Phenylpyridine-2-carboxylate is a bidentate ligand with very strong coordination capacity, some complexes using it as a ligand have been synthesized and structurally characterized in previous studies of our group [10], [11], [12], [13], [14]. In this paper, another new dinuclear Co(II) complex has been synthesized using Co(CH3COO)2·4H2O, 1H-pyrazol-3-ylamine, 6-phenylpyridine-2-carboxylic acid, and NaOH. The results of structural analysis show that the dinuclear Co(II) complex contains two Co(II) ions, four 6-phenylpyridine-2-carboxylate ligands, two 1H-pyrazol-3-ylamine ligands (Figure 1). Two Co(II) ions are bridged by nitrogen atoms of two 1H-pyrazol-3-ylamine ligands. Each Co(II) ion is six-coordinated with two nitrogen atoms and two oxygen atoms of two different 6-phenylpyridine-2-carboxylate ligands, and two nitrogen atoms of two different 1H-pyrazol-3-ylamine ligands, forming a distorted CoN4O2 octahedron with O1 and O3 atoms in the axial position (O1–Co1–O3, 166.67(8)°). The Co–N distances are 2.178(2)–2.332(2) Å (Co1–N1, 2.332(2) Å; Co1–N2, 2.199(2) Å; Co1–N3a, 2.223(2) Å; Co1–N4, 2.178(2) Å) and the Co–O distances are 2.0299(19)–2.0446(19) Å (Co1–O1, 2.0446(19) Å, and Co1–O3, 2.0299(19) Å). The complex molecules are connected to each other through N–H⋯O hydrogen bonds between the 1H-pyrazol-3-ylamine molecules and the 6-phenylpyridine-2-carboxylate ligands to form a 1D chained structure.
