The new nickel(II) complex [ Ni{BBN(pz) 2 }(o-tol)(PPh 3 )] (1) of the bis(pyrazolyl)borate ligand [BBN(pz) 2 ] -(BBN = 1,5 borabicyclo[3.3.1]nonane) has been prepared by reaction of [Ni-Br(o-tol)(PPh 3 ) 2 ] with K[BBN(pz) 2 ]. In the presence of moisture this reaction yields the nickel(II) complex
