摘要
Lanthanide cryptates of a phenol-bridged N8O3 Schiff-base cryptand (H3L) have been synthesized by transmetallation with the sodium cryptate [Na(H2L)], where the cryptand was obtained by a basic template condensation of tris(2-aminoethyl)amine and 2,6-diformyl-4-methoxyphenol. The structure of [EuL(OH2)]·[Eu(HL)(NCS)]·9H 2O·2MeCN·EtCN·EtOH showed the coexistence in the same crystal of two kinds of unsymmetric eight-co-ordinate europium(III) cryptates with different second ligands. The Eu-NCS linkage in [Eu(HL)(NCS)] is linear [Eu-N≡C-S 175(2), N≡C-S 179(2)° and Eu-N 2.42(1) Å].
