Abstract

Abstract The ligands 1-H 6 and 2-H 6 are prepared by condensation of the triangular triamines 5 and 2, 3-dihydroxybenzoic acid hydrazide 7. The ligands form container-type tetrahedral coordination compounds M x [(1 or 2) 4 M′ 4](M= Li, Na, K; M′= Ti, x= 8; M′= Ga, x= 12). The complexes are characterized by NMR spectroscopy and ESI mass spectrometry. Despite the relatively labile acyl hydrazone unit, the complexes show high ...
