“…The structure of 2 was refined, taking into account the disorder of tert-butyl groups and 1,6-diaminohexane using standard constraints (ISOR, DFIX, RIGU, EADP). The structure of 3 was solved, taking into account twinning (twin -1 0 0 0 -1 0 0 0 -1, Flack parameter is 0.113 (18)). Crystallographic parameters and structure refinement details are given in Table 4.…”

“…Coordination polymers are formed by binding metal ions or metal-containing cores with bridging ligands, whose variation in structure-forming parameters allows for control over the polymer's structure [1][2][3][4][5][6][7][8][9][10], as well as luminescent [11][12][13][14], sorption [4,[15][16][17][18], magnetic [19][20][21][22], and other properties. Iron(II) coordination polymers exhibit selective catalytic activity in the hydroboration of aldehydes and ketones [23], the oxidative functionalization of alkanes [24], and in dimerization reactions of aromatic halogen derivatives [25].…”

Interaction of the pre-organized complex of iron(II) trimethylacetate and 1,10-phenanthroline (phen) [Fe2(piv)4(phen)2] (1) (piv = (Me)3CCO2−)) with 1,6-diaminohexane (dahx) in anhydrous acetonitrile yielded a 1D coordination polymer [Fe3O(piv)6(dahx)1.5]n (2) and an organic salt of pivalic acid (H2dahx)(piv)2 (3). The structure of the obtained compounds was determined by single-crystal X-ray diffraction analysis. The phase purity of the complexes was determined by powder X-ray diffraction analysis. According to the single-crystal X-ray analysis, coordination polymer 2 is formed due to the binding of a triangular carboxylate core {Fe3(μ3-O)(μ-piv)6} with an aliphatic diamine ligand. Thermal behavior was investigated for compounds 1 and 2 in an argon atmosphere.

“…Metal-organic coordination polymers (MOCPs) have attracted significant research attention due to their broad structural design [1][2][3] and targeted modulation of properties that is possible by varying functional metal centers [4], organic ligands [5], and guest substrates [6]. Polynuclear and polymeric blocks consisting of unpaired electron-rich metal ions can present valuable magnetic properties (such as ferro- [7], antiferro- [8], and ferrimagnets [9], as well as slow magnetic relaxation [10,11]), complex luminescence patterns [12,13], redox behavior [14], and unique chemical bonding features [15].…”

A reaction between copper(II) nitrate and trans-1,4-cyclohexanedicarboxylic acid (H2chdc) carried out under hydrothermal conditions led to a new metal-organic coordination polymer [Cu2(Hchdc)2(chdc)]n. According to single-crystal XRD data, the compound is based on bi-nuclear paddlewheel-type carboxylate blocks that are joined with polymeric chains due to the (μ3-κ1:κ2) coordination of carboxylate groups. The chains are interconnected by chdc2− bridging ligands into layers containing free COOH groups of terminal Hchdc−. The neighboring layers adopt a RCOOH···OOCR hydrogen bond-assisted arrangement into a dense-packed structure. Magnetization measurements showed the presence of a strong antiferromagnetic exchange interaction (J/kB = −495 K) inside the bi-nuclear blocks. At the same time, no significant interaction was found between the {-Cu2(OOCR)4-} units in spite of their polymeric in-chain packing. Patterns of magnetic behavior of [Cu2(Hchdc)2(chdc)]n were thoroughly analyzed and explained from a structural point of view.

The crystal structures of nine hexamethyl-[1,1′-biphenyl]-4,4′-diammonium (HMB) salts are described: the iodide (2), triiodide (3), succinate (4), fumarate (5), tetravanadate (6), hydroterephthalate (7) and perylenetetracarboxylate (8), as well as pentamethyl-[1,1′-biphenyl]-4,4′-diammonium iodide (1) and the metal–organic framework sodium diacetylenedisalicylate–HMB (9). HMB carbonate (10) has been synthesized as an important intermediate for a promising anti-metal–organic framework (`anti-MOF'). All the described compounds are characterized by high solubility in water. The results suggest that, during crystallization, crystallohydrates are formed from water. Compounds 6 and 9 are characterized by the presence of a rigid framework; compound 6 has an open framework structure filled with water molecules. Synchronous thermal analyses of compounds 2, 4, 6, 7, 8 and 10 allowed the identification of similarities in the mechanisms of thermolysis. At about 80–180°C, the loss of crystallization water molecules occurs. Between 180 and 250°C, a methyl group (methyl cation) is split off from the quaternary ammonium salt to form tetramethylbenzidinium. In the case of the iodides and salts of organic acids, the second thermolysis product is the methyl ester of this acid (methyliodide, dimethyl carbonate), which easily evaporates. In the range 240–355°C, tetramethylbenzidinium evaporates without decomposition.
