In the crystal structure of the pentapeptide Boc0—Gly1–ΔZPhe2—Gly3–ΔZPhe4—Gly5—OMe, C30H35N5O8, the values of torsion angles Φ and Ψ show the presence of two type III′β‐turns, at the ΔZPhe2 and Gly3 residues, and Gly3 and ΔZPhe4 residues. All amino acids in the peptide are linked trans to each other. Two intramolecular N—H⋯O hydrogen bonds, between CO and NH groups, stabilize β‐turns present in the peptide.

“…Several boronic acids have been evaluated as sources of boron for their potential use in a form of cancer therapy (Yang et al, 2003;Deagostino et al, 2016;Zhu et al, 2020;Kumar et al, 2020). Also, boronic acids are generally used in the field of agrochemicals (Torborg and Beller, 2009), organic chemistry (Yang et al, 2002;Ejsmont et al, 2003), inhibitors of proteases (Khangulov et al, 1995;Carvajal et al, 1996). Therefore, this research addresses the synthesis and crystallization of magnetic materials with the use of boronic acid ligands.…”

In this work, the novel compound [HNC 5 H 4 B(OH) 2 -4][Pt(CN) 4 ] (1) has been synthesized and structurally characterized. The compound (1) crystallizes in monoclinic, space group P2 1 /c, a=5.6159(11) Å, b=14.656(3) Å, c=11.619(2) Å, =90, β= 110.35(3), γ=90, V= 896.6(3) Å 3 , Z=2. The optimum molecular geometry parameters have been investigated with the DFT/B3LYP method. All geometric parameters are found in good agreement with crystallographic and computational results. Contributions of fragments molecular orbitals (HOFO-LUFO) to frontier molecular orbitals (HOMO-LUMO) are calculated charge transferred from Pt moiety to other fragments.
