New pyrazolate ligation modes continue to be uncovered : [Sc 2 (Ph 2 pz) 6 ] ( 1 ; Ph 2 pz=3,5‐diphenylpyrazolate) displays the new μ ‐ η 2 : η 1 binding mode and [Nd( η 2 ‐Me 2 pz) 2 ( η 1 ‐Me 2 pz)(Me 2 pzH) 2 py)] ( 2 ; Me 2 pz=3,5‐dimethylpyrazolate; py=pyridine) displays the first example of unidentate η 1 (N) coordination of a pyrazolate to a lanthanide ion.
