“…By varying the substituents in the methylene group of malonic acid, it is possible to change the structure and properties of the resulting compounds, which was previously demonstrated for homometallic complexes of manganese(II), − cobalt(II), − nickel(II), , copper(II), − etc. Moreover, the structure of malonate complexes of transition metals, and hence their properties, can be changed by introducing atoms of s-, d-, or f-elements into a compound. − To date, vast data on the synthesis, structural features, and properties of transition metal complexes (with the exception of iron) with anions of substituted malonic acids and atoms of s-elements have been collected.…”

Three FeIII-MI heterometallic complexes with anions of cyclobutane-1,1-dicarboxylic acid (H2cbdc) dianions [MIFe(cbdc)2(H2O)2] n (MI = Na (1), Rb (2) or Cs (3)) were obtained, with the compounds being two-dimensional (2D)-coordination polymers built of bischelate moieties {Fe(cbdc)2(H2O)2}− bound with alkali metal ions. In 1, the two coordinated water molecules are in the cis-position, while in 2 and 3 they are in the trans-position. The DC magnetic data and ab initio calculations demonstrate that Fe3+ ions in 1 possess a negative D value, while those in 2 and 3 have a positive D value. The easy-axis anisotropy found for 1 is a rare example for Fe3+ ions. A topological analysis of the compounds synthesized and a series of known mononuclear octahedrally coordinated Fe3+ complexes (from Cambridge Structural Database) that are interconnected into a crystal structure by alkali metal cations in a way similar to complexes 1–3 was carried out.

The reaction of VOSO 4 with K 2 cbdc (cbdc 2is cyclobutane-1,1-dicarboxylate anion) and Ln(NO 3 ) 3 (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Y, Er, Tm, Yb, Lu) yielded 17 novel heterometallic Ln III -V IV compounds comprising stable bischelate units {V IV O(cbdc) 2 (H 2 O)}. Three structural types of compounds are formed depending on the nature of the rare-earth metal: 1D polymers {[Ln(VO)(cbdc) 2 (H 2 O) 7 ]·0.5[VO(cbdc) 2 ]} n (structural type I) [Ln = La (1), Ce (2)], 3D polymers {[KLn(VO) 2 (cbdc) 4 (H 2 O) 9 ]·3.5H 2 O} n (structural type II) [Ln = La 5075 [Ln = Y (13), Er (14), Tm (15), Yb (16), Lu (17)] containing dinuclear units {LnV}. Magnetic properties were investigated for all isolated compounds. The Gd III -V IV compound has ferromagnetic and antiferromagnetic exchange interactions between isotropic V IV and Gd III ions. Calculations using the DFT method at the UB3LYP/6-31G(d,p)/SDD level of theory were performed in order to explain the different nature of exchange interactions in two Gd III -V IV pairs. The Yb III -V IV complex displays single-molecule magnet properties; the effective energy barrier was estimated at ΔE eff /k B = 26 K. The magnetic properties of Ln III -V IV compounds with heavy lanthanide ions (Ln III = Er, Tm, Yb) were rationalized in terms of crystal-field calculations for Ln III ions. and clear magnetic hysteresis of purely molecular origin, which are characteristic of single-molecule magnets (SMM). [3] Complexes of 3d-4f metals are considered as good candidates for SMMs due to high anisotropy of some lanthanide ions (Tb III , Dy Meanwhile 3d-4f compounds containing a vanadyl ion V IV O 2+ as the 3d center with a single 3d electron (S = 1 / 2 ) are quite rare, although they may provide insight into the mechanism of spin-spin exchange interactions. Despite quite a large number of V IV -4f complexes were described in recent literature, [11] only a few of them were magnetically characterized. [11a,11b,11d,11e,11g,11j,11l] For example, some V IV -Ln III complexes with ferromagnetically coupled V IV and Ln III ions have been reported. [11d,11e] Ishida et al. [11j] performed AC magnetic susceptibility measurements for five isostructural V IV -Ln III complexes, but these compounds did not exhibit SMM behavior. Besides, 3d-4f complexes are of interest as precursors of complex oxides. [12] One synthetic approach to prepare 3d-4f compounds is based on the use of stable 3d-metal complexes with free functional groups capable of acting as metal-containing ligands, Eur. J. Inorg.
