Tetra(3-iso-propylpyrazol-1-yl)borate ligand (L) forms mono-ligand LMX and bis-ligand L2M complexes (where M=Ni(II), and Cu(II), and X=Cl− or NO3 −) depending on the stoichiometry of the synthesis, while a polynuclear (NCS)2Co(L)Co(L)Co(NCS)2 complex is obtained when excess of cobalt(II) thiocyanate is used. The L coordinates to metal ions in a κ3 fashion in LNiCl, LNi(NO3)(5-iPrpzH) and LCuCl(5-iPrpzH), whereas a κ2 binding mode was found in L2Ni and in unique (NCS)2Co(L)Co(L)Co(NCS)2, in which L bridges two metal ions.The X-ray crystallographic structures, spectral and magnetic properties of nickel(II), copper(II) and cobalt(II) complexes with tetra(3-iso-propylpyrazol-1-yl)borate.
