The structural parameter of spin states of <i>C</i> ₁-symmetric four-coordinate cobalt complexes: <i>D</i> ₄.

ABSTRACT: Herein, we reveal the correlation between structure and spin-states for C ₁-symmetric four-coordinate cobalt complexes. A series of C ₁-symmetric four-coordinate cobalt complexes with various steric, electronic, anions and chelation modes were synthesized and characterized. X-ray diffraction studies revealed a structural distortion from square-planar to distorted tetrahedral pyramidal geometry. Combining paramagnetic nuclear magnetic resonance (pNMR), magnetic measurement (SQUID), X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT), the electronic structure with a cobalt(ii) (S _Co = 1/2 to 3/2) ion antiferromagnetically coupled to a radical anion ligand (S _Ligand = 1/2) was established.
