AbstractTetrakis(1‐adamantylcarboxylato)dicopper(II) Cu2(1‐Ad)4 – Synthesis, Structure and X‐/Q‐band EPR InvestigationsThe synthesis and the crystal structure of tetrakis(1‐adamantylcarboxylato)dicopper(II) are reported. [Cu2(1‐Ad)4·2DMF] (1, 1‐Ad = adamantylcarboxylate) crystallizes in the space group $P{\bar 1}$ (Z = 2) with two crystallographically distinguishable complexes in the unit cell. The averaged Cu‐Cu distance of 260.5 pm is smaller than that found for Cu2(ac)4·2H2O. The combination of temperature‐dependent X‐ and Q‐band powder EPR investigations in the temperature range 6 ≤ T ≤ 295 K show the presence of an antiferromagnetically coupled Cu‐Cu dimer and allow a precise determination of the spin‐Hamiltonian parameter. A comparison of those with that derived for Cu2(ac)4·2H2O indicate a higher symmetry within the Cu2O8 central unit of [Cu2(1‐Ad)4·2DMF].
