Published: October 2020

Tri-ethyl-ammonium hexa-bromido-uranate(IV) di-chloro-methane monosolvate, [(CH)NH][UBr]·CHCl, was obtained in the form of dark-brown crystals from the reaction of uranium penta-bromide with NEt and ethyl-ene glycol in di-chloro-methane at low temperature. During the progress of the reaction, the reduction of uranium(V) to uranium(IV) was observed, whose associated oxidation product could not be identified. The uranium atom of the [UBr] anion is coordinated by six bromido ligands in the shape of an octa-hedron. Between cations, anion and solvent mol-ecules of crystallization, numerous C-H⋯Hal hydrogen-bond-like inter-actions are present, leading to a three-dimensional network structure.

Two new zinc(II) complexes, tri-ethyl-ammonium di-chlorido-[2-(4-nitro-phen-yl)-4-phenyl-quinolin-8-olato]zinc(II), (CHN){Zn(CHNO)Cl] (), and bis-(tri-ethyl-ammonium) {2,2'-[1,4-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato}bis-[di-chlorido-zinc(II)], (CHN)[Zn(CHNO)Cl] (), were synthesized and their structures were determined using ESI-MS spectrometry, H NMR spectroscopy, and single-crystal X-ray diffraction. The results showed that the ligands 2-(4-nitro-phen-yl)-4-phenyl-quinolin-8-ol () and ,'-bis-(2-hy-droxy-benzyl-idene)benzene-1,4-di-amine () were deprotonated by tri-ethyl-amine, forming the counter-ion EtNH, which inter-acts an N-H⋯O hydrogen bond with the ligand. The Zn atoms have a distorted trigonal-pyramidal () and distorted tetra-hedral () geometries with a coord-ination number of four, coordinating with the ligands N and O atoms.

The reaction between 3,3'-[(3-meth-oxy-4-hy-droxy-phen-yl)methanedi-yl]bis-(4-hy-droxy-2-chromen-2-one) and tri-ethyl-amine in methanol yielded the title compound tri-ethyl-ammonium 3-[(4-hy-droxy-3-meth-oxy-phen-yl)(4-hy-droxy-2-oxo-2-chromen-3-yl)meth-yl]-2-oxo-2-chromen-4-olate, CHN·CHO or (NHEt)(CHO), which crystallized directly from its methano-lic mother liquor. The non-deprotonated coumarol substituent shares its H atom with the deprotonated coumarolate substituent in a short negative charge-assisted hydrogen bond in which the freely refined H atom is moved from its parent O atom towards the acceptor O atom, elongating the covalent O-H bond to 1.18 (3) Å.

IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: bis-(tri-ethyl-ammonium) 2,5-di-chloro-3,6-dioxo-cyclo-hexa-1,4-diene-1,4-diolate], 2C6H16N(+)·C6Cl2O4 (2-), the chloranilate anion lies on an inversion center. The tri-ethyl-ammonium cations are linked on both sides of the anion via bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds to give a centrosymmetric 2:1 aggregate. The 2:1 aggregates are further linked by C-H⋯O hydrogen bonds into a zigzag chain running along [01-1].
