Highlights: [•] Two pairs of rac- and meso-diastereomers were successfully separated. [•] Photolysis of (CMe2)(C9H7)(η 5-C9H6)Re(CO)3 (1) yielded the novel product (CMe2)[(η 5-C9H6)(η 2-C9H7)]Re(CO)2 (3). [•] Molecular structures of all compounds were determined by X-ray diffraction.

Graphical abstract Three series of Ln-CPs based on 1,3-adamantanediacetic acid are synthesized and the structure variation is analyzed. The luminescence of Eu- and Tb-CPs is studied. Highlights • Three series (3D, 2D and 1D) of Ln-CPs single crystals were obtained. • The structure variation was analyzed. • The luminescence of Ln-CPs was investigated. Abstract We report the synthesis of 3D Ln-CPs [Tb 2 (ADA) 3 ] n (1a , H 2 ADA = 1,3-adamantanediacetic Acid), 2D Ln-CPs [Ln 2 (ADA) 3 (dmp) 2 ] n ·2EtOH·H 2 O, (Ln3+ = Eu3+, 2a ; Gd3+, 2b ; Tb3+, 2c ; dmp = 4,7-dimethyl-1,10-phenanthroline), and 1D Ln-CPs [Ln(ADA)(HADA)(H 2 O)] n (Ln3+ = Eu3+, 3a ; Gd3+, 3b ; Tb3+, 3c), by introducing the ligand H 2 ADA. The Ln-CPs are characterized by single-crystal X-ray diffraction, PXRD, TGA, elemental analysis and FT-IR. Structure variation is analyzed and suggestions are given for obtaining different types of structures. Luminescence spectra, lifetimes and quantum yields (QYs) are investigated. [ABSTRACT FROM AUTHOR]
