Syntheses, Structural Characterization of Fe and Ni Complexes with Polypyrazolyl Borate Ligand:Fe[HB(pz)3]2 and Ni[HB(pz

Fe(Ⅱ) complex Fe[HB(pz)3]2(compound 1, pz=pyrazole) and Ni(Ⅱ) complex Ni[HB(pz)3]2(compound 2) have been obtained by the reaction of MCI2(M=Fe and Ni) with NaHB(pz)3 in MeOH. The two complexes(compounds 1 and 2) were characterized by IR, NMR, elemental analysis and X-ray diffraction. Compound 1 crystallizes in space group P21/c with a=1.224(3) nm, b=1.161(2) nm, c=1.648(3) nm, β=107.62(15)°, V=2.233(8) nm3, Z=2. Compound 2 crystallizes in space group P21/c with a=0.97926(18) nm, b=1.7423(3) nm, c=1.3156(2) nm, β=97.055(16)°, V=2.2277(7) nm3, Z=4. The results of X-ray structural analyses show that both compounds 1 and 2 are monomeric neutral, possessing a similar coordination mode and a similar structure around the metal centers. The related spectral characterizations, steric effects and binding properties are discussed.
