This critical review presents a comprehensive study of transition-metal carboxylate clusters which may serve as secondary building units (SBUs) towards construction and synthesis of metal-organic frameworks (MOFs). We describe the geometries of 131 SBUs, their connectivity and composition. This contribution presents a comprehensive list of the wide variety of transition-metal carboxylate clusters which may serve as secondary building units (SBUs) in the construction and synthesis of metal-organic frameworks. The SBUs discussed here were obtained from a search of molecules and extended structures archived in the Cambridge Structure Database (CSD, version 5.28, January 2007) which included only crystals containing metal carboxylate linkages (241 references).

“…Frequency-dependent M ′′ signals have been observed in the ac susceptibility studies of all Mn 12 SMMs and are considered a diagnostic signature of the SMM property. 2,4,20,21 In addition, ac magnetic susceptibility data can be employed to obtain the effective energy barrier (U eff ) for magnetization relaxation and even the spin of the ground state. 21 For these reasons, ac susceptibility studies were performed on complexes 5 and 6.…”

“…These anisotropic high spin molecules exhibit original magnetic properties such as single molecule magnet behaviour [12,13,14,15,16,17] (long relaxation time for the magnetisation below a so-called blocking temperature, T B ) or magnetic quantum tunnelling effect [18,19]. Our research approach is devoted to the synthesis of such complexes in order to get single molecule.…”

(dienpy2)]2](ClO4). The ground state spin value is 7/2 for the three systems (ferromagnetic interaction between chromium(III) and nickel(II) ions). The magnetisation of the three CrNi2 complexes was measured using an array of microSQUIDs in a temperature range between 0.04 K and 7 K, under a magnetic field up to 1 T. The three samples present a three dimensional magnetic ordering. The correlation between the structure and the intermolecular coupling is analysed in terms of steric hindrances of the terminal ligand, orientation of the molecules in the unit cell (canted structure) and crystal symmetry.
