| Abstract: | Searching for prospective luminescent materials, the series of new lanthanide coordination compounds CsLnL4 (Ln = La, Pr, Nd, Sm – Er, and Yb; L? = {C6H5CONPO(OCH3)2}-) was synthesized. X-ray diffraction studies of CsNdL4 and CsYbL4 have been performed establishing polymeric structures of the tetrakis-complexes built from LnL4]? anions and cesium cations functioning as linkers. The IR, absorption, emission, excitation spectra, and decay time measurements at 298 and 77 K, as well as thermal gravimetric analyses, were used to characterize the complexes. |
