Abstract

Abstract : Direct thermally induced reactions between rare earth metals (Ln = Y, Ce, Dy, Ho and Er) activated by Hg metal and 3, 5‐di‐phenylpyrazole (Ph2pzH) or 3, 5‐di‐tert‐butylpyrazole (tBu2 pzH) yielded either homoleptic or heteroleptic complexes. The most notable feature is the 7‐coordinate dimer for [Dy2 (Ph2 pz)6 ] with rare μ‐ η 2 : η 1 coordination, which gives a structural and coordination number discontinuity between the 9, 10‐coordinate La, Ce, Nd complexes and the 8‐coordinate dimeric Ho complex. More details are discussed in the article by Nazli E. Rad, Peter C. Junk, Glen B. Deacon, and Jun Wang on877 ff.
