要 旨 :
Anilate-type ligands ([C6O4X2]2- = dianion of the 3,6-disubstituted derivatives of 2,5 dihydroxy-1,4-benzoquinone, H4C6O4) are quite old ligands that have been used for many years to prepare many 0D, 1D, 2D and 3D homo-metallic compounds with different metal ions.[1] Very recently we started to use them to prepare hetero-metallic extended structures (1D, 2D and 3D)[2] showing ferrimagnetic long range ordering whose ordering temperatures could be tuned by simply changing the X group. Given the similarity of the anilato and oxalato ligands, we can anticipate that a vast field in now open with some advantages for the anilato ligand when compared with oxalato: (i) Anilato-type ligands can be modified by changing X, (ii) the hexagonal cavities are twice larger for anilato that for oxalato and (iii) the electronic features of these cavities can be tuned by changing X. Here we will show our recent results obtained using anilato-type ligands to prepare a plethora of molecular materials with different dimensionalities and properties.[3,4] [1] S. Kitagawa, S.
