Zero-Field SMM Behavior Triggered by Magnetic Exchange Interactions and a Collinear Arrangement of Local Anisotropy Axes in a Linear Co₃^II Complex.

ABSTRACT: A new linear trinuclear Co(II)₃ complex with a formula of [{Co(μ-L)}₂Co] has been prepared by self-assembly of Co(II) ions and the N₃O₃-tripodal Schiff base ligand H₃L, which is obtained from the condensation of 1,1,1-tris(aminomethyl)ethane and salicylaldehyde. Single X-ray diffraction shows that this compound is centrosymmetric with triple-phenolate bridging groups connecting neighboring Co(II) ions, leading to a paddle-wheel-like structure with a pseudo-C₃ axis lying in the Co-Co-Co direction. The Co(II) ions at both ends of the Co(II)₃ molecule exhibit distorted trigonal prismatic CoN₃O₃ geometry, whereas the Co(II) at the middle presents an elongated trigonal antiprismatic
