Zn10(Im)20·4DBF: an unprecedented 10-nodal zeolitic topology with a 10-MR channel and 10 crystallographically independent Zn atoms.

By using a large-size amide, dibutylformamide (DBF), as a structure directing agent, a new zeolitic imidazolate framework (ZIF) was synthesized. The ZIF Zn10(Im)20·4DBF has an unprecedented zeolitic topology and features 10 crystallographically independent Zn atoms, a 10-membered ring (MR) channel and an unusual 4-connected 10-nodal net.
