Two new tripodal ligands designed to anchor complexes onto surfaces have been synthesized. They integrate ester or thioether functions at the 6‐position of the indazoles. Potassium hydrotris[6‐(ethoxycarbonyl)indazolyl]borate and potassium hydrotris{6‐[(ethylsulfanyl)methyl]indazolyl}borate exhibit three pendant groups oriented to anchor complexes onto an oxide and a metallic surface, respectively. Their complexation with [RuCp(CH 3 CN) 3 ]PF 6 yielded two piano‐stool‐shaped complexes that were characterized by X‐ray diffraction. Comparison with the synthesized unfunctionalized analog showed that the three 6‐substituted functions do not interfere with the coordination site and are particularly well oriented for surface deposition.(© Wiley‐VCH Verlag GmbH & Co.
