Structural diversity through ligand flexibility: two novel metal-organic nets via ligand-to-ligand cross-linking of paddlewheels

Solvothermal reaction of a partially flexible ligand, H4L, and Cu(NO3)(2)center dot 2.5H(2)O afforded two cross-linked Kagome lattices of formula [Cu-2(L)](n): an acs net sustained by novel trigonal prismatic supermolecular building blocks (SBBs) and the first example of a partially pillared Kagome net.
