Synthesis and Complex Chemistry of Functionalised Tripod Ligands RC(CH 2 PPh 2 ) 3 Malonic ester 1 is alkylated and converted into the triols RC(CH 2 OH) 3 ( 5 ). These are easily converted into the corresponding functionalised tripodal ligands RC(CH 2 PPh 2 ) 3 ( 7 ) with R Bzl ( a ), n ‐C 12 H 25 ( b ), (CH 3 ) 2 CH(CH 2 ) 2 ( c ). Crystals suitable for X‐ray crystallography have been obtained of the ligand 7a . In addition, the tripod ligands 7a and 7c have been further characterized by the syntheses and X‐ray analyses of the nickel complex [( 7a )NiCl] ( 8a ), the iron complex [( 7c )Fe(NCCH 3 ) 3 ](BF 4 ) 2 [ 9 · (BF 4 ) 2 ], and the cobalt complex [( 7c )Co{O(O)CCH 3 }](BPh 4 ) ( 10 · BF 4 ).
