The lines of force are divided equally between the bonds to the corners of the coordination polyhedron.
In both cases, the potassium ions are in an irregular coordination polyhedron.
The cobalt coordination polyhedron is a distorted tetrahedron.
The nickel ions are 6 coordinate with a distorted octahedral coordination polyhedron where columns of octahedra share opposite faces.
A wide variety of ligands that chelate in the cis fashion already exist, but very few can link opposite vertices on a coordination polyhedron.
The "coordination polyhedron" is therefore hollow, and resembles a pyramid (illustrated top right, where the top, blue atom, is the "central" atom).
Regular hexagonal close packing of spheres would predict that each atom is had 12 nearest neighbours and a triangular orthobicupola (also called an anti cuboctahedron or twinned cuboctahedron) coordination polyhedron.
Solids with lattice structures which includes metals and many inorganic solids can have regular structures where coordinating atoms are all at the same distance and they form the vertices of a coordination polyhedron.
It is classified as a polyamine tripodal ligand, i.e., capable of binding to metal ions through three sites and hence is a tridentate chelating ligand, occupying a face of the coordination polyhedron.
