【 摘 要 】
In the title complex, [CoCl2(C25H21N5)], the CoII atom is coordinated by two Cl atoms and two N atoms, provided by a tridentate pyrazolylpyridyl ligand, forming a slightly distorted tetrahedral geometry [range of angles: 96.51 (10) (chelate ring) to 118.60 (9)°]. The dihedral angle between Cl/Co/Cl and N/Co/N planes is 86.83 (7)°. The chelate ring has the conformation of a distorted boat. The dihedral angle between pyridyl ring and the coordinated pyrazolyl ring is 56.16 (12)°. The uncoordinated pyrazolyl ring is almost perpendicular to the pyridyl ring with the dihedral angle of 87.49 (10)°. In the crystal packing, intermolecular phenyl-C—H ⋯π(pyridyl) interactions generate dimeric aggregates. These are connected into a zigzag supramolecular chain along the c-axis direction via π–π interactions [inter-centroid distance between pyridyl and phenyl rings = 3.664 (2) Å].
