Preparation and Spectroscopy of Lanthanide Single Crystals with Isoleucine

Single crystals of lanthanide complexes (Ln = Pr, Nd, Eu) were obtained from aqueous solutions. Optical properties of the title compound are investigated by absorption, excitation, and emission spectra. Probabilities of electronic transitions were analysed and participation of vibronic components in the spectra were found. Temperature effect on the spectra was studied and analysed in terms of cooperative interaction

Thallium(I) Complexes of Cyano-Substituted Bispyrazolylborate Ligands

Click on the DOI link below to access the article (may not be free).Two thallium scorpionate complexes: dihydrobis(3-phenyl-4-cyanopyrazolyl)boratothallium(I) (TlBp(Ph,4CN)), C20H14BN6Tl and dihydrobis(3-tert-butyl-4-cyanopyrazolyl)boratothallium(I) (TlBp (t-Bu,4CN)), C16H22BN6Tl have been prepared and characterized by X-ray diffraction. Both compounds crystallize in monoclinic space groups, TlBp(Ph,4CN) in P2(1)/n with a = 4.2039(3) , b = 26.2211(17) , c = 16.611(1) , beta = 90.199(3)A degrees, and TlBp (t-Bu,4CN) in P2(1)/c with a = 13.8578(5) , b = 9.6741(4) , c = 14.2790(5) , beta = 95.141(2)A degrees. The two complexes show similar structures with elongated metal-ligand bonds and intermolecular interactions between the metal ion and cyano substituents, allowing the potential construction of cyano-bridged coordination polymers.The authors thank Drs.
