Unprecedented intramolecular pancake bonding in a {Dy 2} single-molecule magnet
Inorganic Chemistry Frontiers, 2020•pubs.rsc.org
The first example of unique coordination induced intramolecular pancake bonding was
achieved through the reduction of two bis (pyrazolyl)-tetrazine ligands, affording [MIII2 (μ-
(bpytz) 2)(THMD) 4](M= Dy, Y; bpytz= 3, 6-bis (3, 5-dimethyl-pyrazolyl)-1, 2, 4, 5-tetrazine;
TMHD= 2, 2, 6, 6-tetramethyl-3, 5-heptanedionate). To provide a cohesive magneto-
structural correlation, the mono bis (pyrazolyl)-tetrazine bridged congener [DyIII2 (μ-
bpytz)(THMD) 6]· 4 (C6H6) was also isolated. Both metal complexes exhibit single-molecule …

The first example of unique coordination induced intramolecular pancake bonding was achieved through the reduction of two bis(pyrazolyl)-tetrazine ligands, affording [MIII2(μ-(bpytz)2)(THMD)4](M = Dy, Y; bpytz = 3,6-bis(3,5-dimethyl-pyrazolyl)-1,2,4,5-tetrazine; TMHD = 2,2,6,6-tetramethyl-3,5-heptanedionate). To provide a cohesive magneto-structural correlation, the mono bis(pyrazolyl)-tetrazine bridged congener [DyIII2(μ-bpytz)(THMD)6]·4(C6H6) was also isolated. Both metal complexes exhibit single-molecule magnet behaviour under an applied dc field.
