Influence of oxazolidines and zirconium oxalate crosslinkers on the hydrothermal, enzymatic, and thermo mechanical stability of type 1 collagen fiber

Crystallized powder of dihydroxide zirconium oxalate Zr(OH) 2 (C 2 O 4 ) ( ZrOx ) was obtained by precipitation and the structure determined from powder X-ray data. The three-dimensional (3D) framework observed in ( ZrOx ) results from the interconnection of zirconium hydroxide chains 1 ∞ [Zr(OH) 2 ] 2+ and zirconium oxalate chains 1 ∞ [{Zr(C 2 O 4 )} 2+ ]. Single crystals of (H 11 O 5 ) 2 [Zr 2 (C 2 O 4 ) 5 (H 2 O) 4 ] ( H2Zr2O5 ) were obtained by evaporation. The structure contains dimeric anions [Zr 2 (C 2 O 4 ) 5 (H 2 O) 4 ] 2– connected through hydrogen bonds to hydroxonium ions (H 11 O 5 ) + to create a 3D supramolecular framework. The addition of ammonium or alkali nitrate led to the formation of single crystals of Na 2 [Zr(C 2 O 4 ) 3 ]·2H 2 O ( Na2ZrOx3 ), M(H 7 O 3 )[Zr(C 2 O 4 ) 3 ]·H 2 O, M = K ( KHZrOx3 ), M = NH 4 ( NH4HZrOx3 ), M(H 5 O 2 ) 0.5 (H 9 O 4 ) 0.5 [Zr(C 2 O 4 ) 3 ], M = Rb ( RbHZrOx3 ), and M = Cs ( CsHZrOx3 ). For the five compounds, the structure contains ribbons 1 ∞ [{ZrOx 3 } 2– ] formed by entities Zr(C 2 O 4 ) 4 sharing two oxalates. In ( Na2ZrOx3 ), the shared oxalates are in cis positions and the chain 1 ∞ [Zr–Ox] is stepped with a Zr–Zr–Zr angle of 98.27(1)°. In the other compounds, the shared oxalates are in trans positions and the chains 1 ∞ [Zr–Ox] are corrugated with Zr–Zr–Zr angles in the range 140.34(1)–141.07(1)°. In the compounds ( MHZrOx3 ), the cohesion between t...

“…Several substituted oxazolidines have been investigated extensively because of their importance as pharmacological active compounds (such as antidiabetic [1], anticonvulsant [2], antitubercular [3], and aldose reductase inhibitors [4]), chiral auxiliaries in the synthesis of a variety of chiral compounds, chain-protecting groups for amino alcohols [5,6], crosslinking agents [7] to stabilization of collagen [8,9], linkers in solid-phase synthesis of peptide aldehydes process [10], optical probe applications [11] and fungicidal activities [12].…”

In this work, two binuclear complexes, fac-[Cd2(AEPC)2(μ-Cl)2Cl2] (1) and [Hg2(AEPC)2(μ-Cl)2Cl2] (2), of 2-(2-(pyridin-2-yl)oxazolidin-3-yl)ethanol (AEPC) were prepared and identified by elemental analysis, FT-IR, 1 H NMR spectroscopies and single-crystal X-ray diffraction. All coordination modes of 2-(pyridin-2-yl)oxazolidine derivatives were studied by analysis of the Cambridge Structural Database (CSD) for determination of coordination behaviors of the AEPC ligand with metals. In the crystal structure of 1, the cadmium atom has a distorted octahedral geometry and CdN2OCl3 environment in which each ligand acts as 2 an NN'O-donor. In the crystal structure of 2, the AEPC acts as NN'-donor toward the mercury atom to form a square-pyramidal geometry with three chloride ions. Each complex contains four chiral centers and R,R,S,S configuration with a center of inversion and Ci symmetry. In the crystal networks of the complexes, the alcoholic group of the ligands participate in hydrogen bonding and form R4 4 (28) and R6 6 (44) hydrogen bond motifs (observed for complex 1). In addition to the hydrogen bonds, the crystal network is stabilized by π-π stacking interactions between pyridine rings of the AEPC ligands of adjacent complexes.
