Zigzag on a zigzag: Trap of hydrogen-bonded water molecules in a luminescent metal-organic network

“Zigzag on a zigzag” is observed in a luminescent metal-organic architecture. The arrangement in a zigzag motif of water molecules look as if the motif is projected out of the zigzag motif of CdII atoms via hydrogen bonds. The emission maximum of the title compound is 525 nm.
