Structures and magnetic anisotropies of two seven-coordinate Co()-nitrate complexes showing slow magnetic relaxation
Two seven-coordinate Co( ii )-nitrate complexes, [Co(tmpdc)(NO 3 ) 2 ] ( 1 ) and [Co(tmpdt)(NO 3 ) 2 ]·CH 3 CN ( 2 ) (tmpdc = N , N , N ′, N ′-tetramethyl-2,6-pyridinedicarboxamide, tmpdt = N , N , N ′, N ′-tetramethyl-2,6-pyridinedithiocarboxamide) with tridentate neutral ligands tmpdc or tmpdt hav...
