Two zinc(II) complexes based on (fluorene-9,9-diyl)di-propanoic acid (H2L) and 1,3-bis(imidazol-1-yl)butane (BIB): Syntheses, crystal structures and luminescent properties

Two supramolecular assemblies (1 and 2) tuned by solvent condition were obtained by reacting (fluorene-9,9-diyl)dipropanoic acid and 1,3-bis(imidazol-1-yl)butane with zinc(II) dichloride, in which a 2D wave-shaped layer formed in 1 and a 2D → 3D inter-penetrated structures were formed in 1 and 2, respectively.64
