摘要：

In the beta form of tris(thiocyanato-N)[2,7,13,18-tetramethyl-3,6,14,17,23, 24-hexaazatricyclo[17.3.1.1(8.12)]-tetracosa-1(23),2,6,8(24),9, 11,13,17,19,21-decaene-N-3,N-6,N-14,N-17,N-23,N-24] europium, the nine-coordinate Eu-III ion is bound to the N atoms of three monodentate isothiocyanate ligands and to the six N atoms of the macrocyclic ligand L (C22H26N6), which has an 18-membered six-N-atom donor cavity, with a coordination geometry analogous to that of the alpha form.
