WebThe overall topology for CP 4 is a 2D uninodal 3-c net with the point symbol (6 3), and possesses the hcb topology. This topology is identical to 1 and 2 , although no halide bridges are involved in extending the inorganic building blocks. WebThus, the topology of CP 1 can be described as a uninodal 3-c (three-connected) net with the point symbol (6 3), as found in the hcb topology (according to RCSR). The same …
