Syntheses and Structures of Two Novel Interdigitated Metal‐Quinolone Complexes: [Cu 2 (cfH) 2 (bptc)(H 2 O)]·4H 2 O and [Zn 2 (levofH) 2 (odpa)]·5.5H 2 O

Two novel interdigitated metal‐quinolone complexes, namely [Cu 2 (cfH) 2 (bptc)(H 2 O)] · 4H 2 O ( 1 ) and [Zn 2 (levofH) 2 (odpa)] · 5.5H 2 O ( 2 ) (bptc = 3,3′,4,4′‐benzophenonetetracarboxylate, cfH = ciprofloxacin, odpa = 4,4′‐oxydiphthalate, levofH = levofloxacin) were synthesized hydrothermally and characterized by elemental analyses, IR spectra, UV/Vis spectra, TG analyses, powder X‐ray diffraction, and single‐crystal X‐ray diffraction. Moreover, solid‐state photoluminescence property of compound 2 was also investigated at room temperature. Compound 1 exhibits a novel interdigitated architecture, which is built from 1D chains with side arms. The structure of compound 2 consists of 1D chains with dangling levofloxacin ligands protruding from both sides of the chain, and these chains are interdigitated with each other to generate a interdigitated framework.
