Directed formation of tri-connected Cu(I) coordination polymers

Two new tri-connected copper(I) coordination polymers have been synthesized, featuring a 1D staircase-like structure and an interpenetrating 2D polycyclohexane framework. The geometries are controlled by steric factors that are generated from the terminal blocking ligand 2-diphenylphosphino-n-methyl pyridine (n = 3, 6) with the methyl group at different substituted positions.
