  Magnetic properties of pentacoordinate complexes of the type [Co(bzimpy)X2], X = Cl and Br, were investigated in DC and AC modes. The DC data shows sizeable zero‐field splitting for these complexes. The AC susceptibility data confirms slow magnetic relaxation at the applied DC field with two relaxation channels. The low‐frequency relaxation time is as slow as τLF ≈ 0.1–0.3 s for the Cl and Br complexes

  The tridentate 2,6-bis(benzimidazolyl)pyridine ligands were combined with CoCl2 to prepare a series of complexes of the general formula: [Py(Bm-R)(2)]CoCl2 (where Py = pyridyl, Bm=benzimidazolyl, R=H (3a); -Me (3b); -Bz (3c)). These complexes were characterized by mass and elemental analysis, along with X-ray diffraction analysis. The geometry around the five coordinated Co atom in 3c consists of a distorted square pyramid in which cobalt is surrounded by tridentate NICA ligand and two chlorines. The Co(II) complexes exhibited high catalytic activities for the polymerization of 1.3-butadiene on activation with alkylaluminums to yield predominantly cis-1,4-polybutadiene with high molecular weight. Choice of cocatalysts was found to be a decisive factor in determining the activity and product microstructure. Ethylaluminum sesquichloride (EASC) was found to be the most efficient one resulting in polymers with about 97% 1,4-cis content. The ligand modification by N-alkylation shows considerable influence on the catalytic activity by virtue of variation of electronic environment of the active centers. The stereoselectivity of the catalysts was consistent for a wide range of reaction conditions, except the formation of a considerable amount of 1,4-trans inserted units at high temperature.

  Temperature variation of the effective magnetic moment for a pentacoordinate [Co(bzimpy)Cl-2] complex shows a pronounced deviation from linearity below 120 K. Quantitative analysis based on the diagonalisation of the spin Hamiltonian matrices gave the set of magnetic parameters: g(x) = 2.501, g(y) = 2.622, g(z) = 1.476, D/hc = 71.7 cm(-1), E/hc = 1.4 cm(-1), alpha(TIP) = 0.98 x 10(-9) m(3) mol(-1) and zJ/hc = -0.184 cm(-1) (SQUID data). The extreme Value of the axial zero-field splitting parameter D shows that the magnetic anisotropy determined by the non-spherical distribution of the spin density is enhanced by the low symmetry of the pentacoordinate chromophore. For the [Mn(bzimpy)Cl-2] . 1/2 MeOH analogue, only a moderate ZFS is found (D/hc = -2.7 cm(-1)). (C) 1999 Elsevier Science B.V. All rights reserved.
