The bright yellow Schiff-base complex Eu(TRENDSAL) (1) (TRENDSAL = N[CH2CH2N=CH(2-OH-3,5-tBu2C6H2)]3) was prepared in 71% yield by treatment of EuCl3x6H2O simultaneously with 3,5-di-tert-butylsalicylicaldehyde and tris(2-aminoethyl)amine in the presence of triethylamine. X-Rax crystal structure analyses of the solvates 1xDME (DME = 1,2-dimethoxyethane) and 1xMeCN demonstrated the tight encapsulation of the Eu3+ ion, allowing not even the "slim" acetonitrile to enter the coordination sphere of europium.
