The crystal structure of Ca\({}_{3}\)Co\({}_{2}\)O\({}_{6}\) consists of chains of Co atoms along the \(c\)-axis, where each cobalt site alternates between trigonal and octahedral coordination with the surrounding oxygen ligands. Additionally, both trigonal and octahedral sites alternate, with each having a 45° rotation about the \(c\)-axis relative to their nearest neighbor (along the \(c\)-axis) of the same coordination. In the \(ab\)-plane (top view), the chains form a triangular-type lattice.
