title: A series of luminescent lanthanide-cadmium-organic frameworks with helical channels and tubes.
abstract: Lanthanide (Ln) oxides and cadmium (Cd) salts as sources of metals provided the first series of luminescent Ln-Cd-organic frameworks, [LnCd(imdc)(SO4)(H2O)3].0.5H2O (Ln = Tb, Eu, Dy, Gd, Er, Yb, Y, Nd, Pr; H3imdc = 4,5-imidazoledicarboxylic acid), in which the Ln atoms are linked by imdc ligands with skew coordination orientation, resulting in novel hetero-metallic-organic frameworks with left-/right-handed helical tubes (L1/R1) and channels (L2/R2) along the b axis.
