Novel coordinating motifs for lanthanide(III) ions based on 5-(2-pyridyl)tetrazole and 5-(2-pyridyl-1-oxide)tetrazole. Potential new contrast agents.
Water-soluble and neutral Ln(III) and Zn (II) complexes of pyridine- and (pyridine-1-oxide)tetrazole have been synthesized and the Gd derivatives have great potential as high-relaxivity low-osmolarity MRI contrast agents.
