Peculiarities of the Interaction of Rare-Earth Metal Thiocyanates with s-Triazine

The reactions of thiocyanates Ln(NCS) 3 ⋅ 6H 2 O (Ln = Y, Eu, and Tb) with 2,4,6-tris(2-pyridyl)- s -triazine (Tptz) in МеОН, MeCN, and H 2 O afford neutral or ionic thiocyanate complexes with one coordinated Tptz molecule. The uniqueness of the complexes is the presence of the second Tptz molecule...

Description
Summary:The reactions of thiocyanates Ln(NCS) 3 ⋅ 6H 2 O (Ln = Y, Eu, and Tb) with 2,4,6-tris(2-pyridyl)- s -triazine (Tptz) in МеОН, MeCN, and H 2 O afford neutral or ionic thiocyanate complexes with one coordinated Tptz molecule. The uniqueness of the complexes is the presence of the second Tptz molecule in the exo coordination. The transformation of Tptz into the endo coordination occurs upon recrystallization from an aprotic solvent. The structural peculiarities of the synthesized compounds are determined by powder X-ray diffraction, IR spectroscopy, and single-crystal X-ray diffraction (CIF files CCDC nos. 1827916–1827921).
