The octahedral [Re 6 Se 8 (CN) 6 ] 4− ions with various bridging metal ions form well‐defined cubic and hexagonal mesostructures (see image) in the presence of liquid‐crystal template in formamide. The interaction between the positively charged micellar head groups of the template and the [Re 6 Se 8 (CN) 6 ] 4− ions is a pure noncovalent electrostatic interaction. These materials are coordination polymers with exceptionally large 1D or 3D potential pores because of the dimension of mesoscale liquid‐crystal template.
