Five new coordination compounds (CCs)of europium(III) and terbium(III) with adamantine-1-carboxylic acid (Had) and 1,10-phenanthroline (phen) are synthesized. The structures of [Tb2(phen)2(ad)6]·Had·20H2O (1), [Eu(ad)3] (2), [Tb(EtOH)2(ad)3] (3), and [Eu2(phen)2(NO3)2(ad)4] (4Eu) are determined by single crystal X-ray diffraction, and isostructural 4Tb CC is obtained. Compounds 2 and 3 are chain polymers, and the use of phen as an ancillary ligand results in the formation of molecular complexes (1 and 4). The luminescent properties are studied of 4Eu and 4Tb compounds in the solidstate. Characteristic emission of Eu3+ and Tb3+ ions is found with quantum yields of 20±1% and 31±2% respectively. The luminescent suspensions based on 4Eu are revealed to be stable in a number of nonpolar and weakly polar solvents. The possible luminescent detection of perfluoroheptane and tert-butanol is visually shown.
