Crystal structure of di-chlorido-{2,6-bis-[(3-phenyl-1H-pyrazol-1-yl)meth-yl]pyridine}cobalt(II).

ABSTRACT: In the title complex, [CoCl2(C25H21N5)], the Co(II) atom is coordinated by two Cl atoms and two N atoms, provided by a tridentate pyrazolylpyridyl ligand, forming a slightly distorted tetra-hedral 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, inter-molecular phenyl-C-H ??(pyrid-yl) inter-actions generate dimeric aggregates. These are connected into a zigzag supra-molecular chain along the c-axis direction via ?-? inter-actions [inter-centroid distance between pyridyl and phenyl rings = 3.664?(2)?Å].
