Cobalt(II) chloride complex with Bi-1, 1'-(3, 3-dimethyl-3, 4-dihydroisoquinoline): Synthesis, crystal structure, and spectra
'Pleiades Publishing Ltd', 2020Co-Authors: Davydov V.v., Sokol V.i., Kolyadina N.m., Polyakova E.i., Palamino M.i.l., Chernov S.a., Shklyaev Yu.v., Sergienko V.s.Abstract:The complex of Cobalt(II) chloride with bi-1, 1'-(3, 3-dimethyl-3, 4-dihydroisoquinoline) (L), [CoLCl2] ( I ), is synthesized and studied by X-ray diffraction, electronic spectroscopy, and IR spectroscopy. In the structure of complex I , ligand L performs a bidentate-chelating function, adding to the Cobalt Atom through the nitrogen Atoms. The coordination polyhedron of the Cobalt Atom is a tetrahedron (2N, 2Cl) with ordinary Co-N (2.00(1)-2.07(1) Å) and Co-Cl (2.216(6)-2.226(6) Å) bond lengths. The noncentrosymmetric orthorhombic unit cell of crystal I contains two independent molecules of the complex (1 and 1') joined by C-H=Cl hydrogen bonds into a pseudocentrosymmetric dimer. Ligands Lc and L'c exist in the same cisoid isomeric form (torsion angle N(1)-C(1)-C(12)-N(2) is 19.2° in Lc and 26.6° in L'c). © Pleiades Publishing, Inc., 2009

Cobalt centred boron molecular drums with the highest coordination number in the cob16 cluster
Nature Communications, 2015Co-Authors: Ivan A Popov, Tian Jian, Gary V Lopez, Alexander I Boldyrev, Laisheng WangAbstract:The electron deficiency and strong bonding capacity of boron have led to a vast variety of molecular structures in chemistry and materials science. Here we report the observation of highly symmetric Cobalt-centered boron drum-like structures of CoB16(-), characterized by photoelectron spectroscopy and ab initio calculations. The photoelectron spectra display a relatively simple spectral pattern, suggesting a high symmetry structure. Two nearly degenerate isomers with D8d (I) and C4v (II) symmetries are found computationally to compete for the global minimum. These drum-like structures consist of two B8 rings sandwiching a Cobalt Atom, which has the highest coordination number known heretofore in chemistry. We show that doping of boron clusters with a transition metal Atom induces an earlier two-dimensional to three-dimensional structural transition. The CoB16(-) cluster is tested as a building block in a triple-decker sandwich, suggesting a promising route for its realization in the solid state.
