【 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].
