“…Zwitterionic λ 5 Si, λ 5 Si′ disilicates containing SiO 4 C skeletons with five‐ring chelates made up of hydroxy‐ and carboxy‐oxygen atoms have recently been investigated 6. Complexes of tartaric acid are also known with elements such as lithium,7,8 antimony,9 bismuth,10 vanadium,11,12 copper,13 cobalt,14 and samarium 15. In each of these compounds, the central metal is coordinated by the most acidic carboxy‐oxygen atom and the α‐hydroxy group.…”

The protective coating on mussel (Mytilus galloprovincialis) byssus has attracted considerable research interest because of its excellent mechanical properties such as hardness and extensibility. These special properties are known to be highly related with specific interactions between mussel foot protein-1 and metal ions. In particular, the complexation between catechols in mfp-1 and iron(III) has been identified as a key interaction. This finding has given opportunities for pursuing promising applications. Herein, we report that emulating the properties of the mussel byssus cuticle provides an important platform for developing reversible layer-by-layer (LbL) deposition, an advanced technique for surface modification. LbL films were constructed on solid substrates by sequential immersion of substrates into solutions containing iron(III) and catecholic compounds. The thickness of the LbL films was effectively controlled by increasing the immersion steps, and the reversibility of the LbL deposition was demonstrated by addition of a chelating agent.

“…Copper (II) tartrate (CuTart) was prepared according to the method described by Al-Dajani et al [18] as follows: In a round-bottomed flask containing about 20 mL of distilled water, tartaric acid was introduced, C 4 H 6 O 6 (150 mg, 1 mmol) and sodium hydroxide, NaOH (80 mg, 2 mmol) which gradually dissolved under magnetic stirring. To the colorless solution obtained was added copper (II) chloride dihydrate, Cu(Cl) 2 .2H 2 O (170.5 mg, 1 mmol).…”

Two coordination compounds, copper (II) fumarate (CuFum) and copper (II) tartrate (CuTart), synthesized from copper (II) with fumaric acid and tartaric acid as ligands and using the slow evaporation method have been applied to study the adsorption of phenacetin in aqueous solution. These compounds were characterized by elemental analysis, IR-FT spectroscopy, and X-ray powder diffraction. The melting points of the synthesized coordination compounds were found to be above 350°C. The influence of parameters such as the initial pH, the contact time, and the initial concentration on the adsorption of phenacetin in an aqueous solution has been studied. The studies showed that adsorption equilibrium was reached after 80 minutes for both coordination compounds; the adsorption capacity increased with increasing phenacetin concentration, and the maximum adsorption capacity was obtained in the acidic medium at pH 4. The adsorbed amount of phenacetin on copper (II) fumarate (CuFum) was 25.158 mg/g while that on copper (II) tartrate (CuTart) was 25.906 mg/g. Nonlinear regression analysis showed the best fit for the Freundlich model isotherm for CuTart with R2 of 0.963 and a Chi-square test (χ2) of 0.529 while for the CuFum material, it is the Redlich-Peterson model with R2 of 0.975 and Chi-square test (χ2) of 0.263. The kinetic study shows that the pseudo-second-order model better describes the adsorption of the two materials. The results show that physisorption and chemisorption participate in the adsorption of phenacetin and that these materials can be used for the elimination of phenacetin in solution.

Crystals of the bis(tert‐butyl)silylene (DTBS) derivatives of the tartaric acids were synthesized from D‐, L‐, rac‐, and meso‐tartaric acid and DTBS bis(trifluoromethanesulfonate): two polymorphs of Si2tBu4(L‐Tart1,2;3,4H–4) (L‐1a and L‐1b), the mirror image of the denser modification (D‐1b) as well as the racemate (2), and the meso analogue Si2tBu4(meso‐Tart1,3;2,4H–4) (3). The structures were determined by single‐crystal X‐ray diffraction. The threo‐configured D‐ and L‐ (and rac‐) tartrates were coordinated by two tBu2Si units forming five‐membered chelate rings, whereas the erythro‐configured meso‐tartrate formed six‐membered chelate rings. The new compounds were analyzed by NMR techniques, including 29Si NMR spectroscopy, and single‐crystal X‐ray crystallography.
