A mononuclear cobalt(II) complex [Co(BP)(Cl(2))], 1 with a new N,N-bidentate ligand, BP ([N,N-(1,1'-biphenyl-2,2'-dimethylene)]-2-aminomethyl) pyridine) was synthesized and characterized by elemental analysis, UV-Vis, paramagnetic NMR, magnetic moment and single crystal XRD. The air and moisture stable Co(II) title complex is a 15 electron species which crystallizes in the monoclinic space group P2(1)/n with cell dimensions a = 10.406(3), b = 12.873(4), c = 13.859(7) angstrom, beta = 96.30(3)degrees and Z = 4. The cobalt atom has distorted tetrahedral (td) geometry with coordination provided by an amine and pyridyl nitrogen donors of BP and two terminal chloride ions. The packing is stabilized through C-H center dot center dot center dot pi and van der Waals interactions.
