“…These complexes are binuclear, which is typical of rare earth metal carboxylates [6][7][8][9][10]. In the structures of the transition metal cyman trenecarboxylate complexes, the O 2 CCym ligands (Cym is (η 5 C 5 H 4 )Mn(CO) 3 ) also behave similarly to other carboxylates [11][12][13][14]. However, in the case of lanthanides of the yttrium group, binuclear cyman trenecarboxylates were synthesized only when dime thyl sulfoxide (DMSO) was used as an additional ligand.…”

New binuclear cymantrenecarboxylate complexes of rare earth metals, [Ln 2 (μ O,η 2 O 2 CCym) 2 (μ 2 O,O' O 2 CCym) 2 (η 2 O 2 CCym) 2 (DMSO) 4 ] (Ln = Tb (I), Dy (II); Cym = (η 5 C 5 H 4 )Mn(CO) 3 ) and [Ln 2 (μ 2 O,O' O 2 CCym) 4 (η 2 -NO 3 ) 2 (DMSO) 4 ] (Ln = Tb (III), Dy (IV)), are synthe sized and characterized by X ray diffraction analysis. The carboxylate clusters containing the Mn 2+ ion, which is formed due to the destruction of the cymantrenenecarboxylate anion, [Tb 4 (μ 3 OH) 4 (μ 2 O,O' O 2 CCym) 6 (H 2 O) 3 (THF) 4 ][MnCl 4] ⋅ 4CH 2 Cl 2 ⋅ 6THF (V) with the cubane like structure, and [Er 2 Mn(μ 2 O 2 CCym) 6 (η 2 O 2 CCym) 2 ((MeO) 3 PO) 4 ] ⋅ 2MePh (VI) with linear structure, are also obtained. The magne tism of complexes I, II, V, and VI is studied in a direct magnetic field. The magnetic properties of complexes II and VI are studied in direct and alternating magnetic fields. Complex II exhibits the properties of a single molecule magnet. The thermal decomposition of complexes I-IV is studied by differential scanning calorim etry and thermogravimetric analysis. According to the X ray diffraction analysis data, the final thermolysis products of complexes III and IV in air are multiferroics LnMn 2 O 5 .

“…Though our group had reported tetraglyme and triglyme complexes of tin(II) triflates, 13 there have only been two other structurally authenticated example of such complexes since then, and recently such complexes have received attention as metal-containing ionic liquid precursors for high-speed metal electrodeposition. 24,25 [SnBr] + fragments of 3.2552(7) Å. While this type of head-to-tail dimerization has been observed for tin(II) chloride fragments (usually featuring strong covalently bound ligands), [26][27][28][29] it is much more rare for cases involving tin(II) bromide, [30][31][32][33]…”

A series of germanium(II) and tin(II) bromide polyether complexes have been synthesized. Specifically, [GeBr([15]crown-5)][GeBr3], [GeBr([18]crown-6)][GeBr3], [GeBr(triglyme)][GeBr3], [GeBr(tetraglyme)][GeBr3], [SnBr([18]crown-6)][SnBr3], [Sn([15]crown-5)2][SnBr3]2, [SnBr(triglyme)][SnBr3], and [SnBr(tetraglyme)][SnBr3] have been fully characterized including by single crystal X-ray diffraction. The synthesis of [GeBr(dibenzo[24]crown-8)][GeBr3] and [GeCl(dibenzo[24]crown-8)][GeCl3] are also reported, along with the crystal structure of the latter’s water adduct, which features a water molecule adjacent to the GeCl+ ion within the cavity of the crown ether.

Development of alternative approaches to fuel components and basic organic synthesis precursors producing based on biomass treatment products is important objective for ecology and chemistry. In this work, a number of original Pt-Sn containing catalysts were used for the mixture of fatty acids conversion. The peculiarities of used catalysts are usage of heterometallic precursors that possesses metal-metal bonds. Such kind of catalysts precursors allow obtaining more active and selective catalysts then ones based on a mixture of monometallic Pt and Sn precursors. Structural peculiarities of catalysts were characterized with TEM&EDS and XAS technique. Relations between Pt clusters structure and its catalytic properties were determined.
