To obtain more structural information of (phthalocyaninato)ruthenium compounds, an EXAFS investigation was carried out on amorphous t Bu 4 PcRu ( 1 ), t Bu 4 PcRu(3‐Clpy) 2 ( 2 ), PcRu(3‐Fpy) 2 ( 3 ) and (C 5 H 11 O) 8 PcRu(3‐Clpy) 2 ( 4 ). Structural models for the four compounds are deduced from the atomic distances determined around the metal centre. A dimeric structure was found for 1 , while bisaxial arrangement of the ligands was shown for 2, 3 and 4 , and the structural parameters were also determined.
