https://www.selleckchem.com/products/crenolanib-cp-868596.html Copper(I) iodide complexes are well known for displaying a diverse array of structural features even when only small changes in ligand design are made. This structural diversity is well displayed by five copper(I) iodide compounds reported here with closely related piperidine-2,6-di-thione (SNS), isoindoline-1,3-di-thione (SNS6), and 6-thioxopiperidin-2-one (SNO) ligands di-μ-iodido-bis-[(aceto-nitrile-κN)(6-sulfanylidenepiperidin-2-one-κS)copper(I)], [Cu2I2(CH3CN)2(C5H7NOS)2] (I), bis-(aceto-nitrile-κN)tetra-μ3-iodido-bis-(6-sulfanylidenepiperidin-2-one-κS)-tetra-hedro-tetra-copper(I), [Cu4I4(CH3CN)4(C5H7NOS)4] (II), catena-poly[[(μ-6-sulfanylidenepiperidin-2-one-κ2OS)copper(I)]-μ3-iodido], [CuI(C5H7NOS)] n (III), poly[[(piperidine-2,6-di-thione-κS)copper(I)]-μ3-iodido], [CuI(C5H7NS2)] n (IV), and poly[[(μ-isoindoline-1,3-di-thione-κ2SS)copper(I)]-μ3-iodido], [CuI(C8H5NS2)] n (V). Compounds I and II crystallize as discrete dimeric and tetra-meric complexes, whereas III, IV, and V crystallize as polymeric twottering effects and to identify the solvent mol-ecules. The given chemical formula and other crystal data do not take into account the solvent mol-ecules.The title compound, C6H11NO2·2H2O2, is the richest (by molar ratio) in hydrogen peroxide among the peroxosolvates of aliphatic α-amino acids. The asymmetric unit contains a zwitterionic pipecolinic acid mol-ecule and two hydrogen peroxide mol-ecules. The two crystallographically independent hydrogen peroxide mol-ecules form a different number of hydrogen bonds one forms two as donor and two as acceptor ([2,2] mode) and the other forms two as donor and one as acceptor ([2,1] mode). The latter hydrogen peroxide mol-ecule forms infinite hydrogen-bonded hydro-peroxo chains running along the c-axis direction, which is unusual for aliphatic α-amino acid peroxosolvates.The title compound, C15H12F3NO, crystallizes with one mol-ecule in the asymmetric unit.
