l-Leucinium fluoride monohydrate
The asymmetric unit of the title hydrated salt, C(6)H(14)NO(2) (+)·F(-)·H(2)O, contains a discrete cation with a protonated amino group, a halide anion and one water mol-ecule. The crystal structure is composed of double layers parallel to (010) held together by N-H⋯O, N-H⋯F, O-H⋯F and C-H⋯F hydrogen bonds, forming a two-dimensional network, and stacked along the c axis, viz. hydro-philic layer...
متن کاملDipotassium hydrogencarbonate fluoride monohydrate
Single crystals of the title compound, K2(HCO3)F·H2O, were obtained as a secondary product after performing flux synthesis experiments aimed at the preparation of potassium rare earth silicates. The basic building unit of the structure is an [(HCO3)(H2O)F](2-) zigzag chain running parallel to [001]. Both types of anions as well as the water mol-ecules reside on mirror planes perpendicular to [0...
متن کاملl-Alanine hydrochloride monohydrate
Colorless crystals of l-alanine hydrochloride monohydrate, C(3)H(8)NO(2) (+)·Cl(-)·H(2)O, were obtained from a powder sample that had been left standing in a refrigerator for a few years. The structure displays several inter-molecular hydrogen bonds: the hydroxyl O atom is involved in a single hydrogen bond to the chloride anion, while the ammonium group forms one hydrogen bond to the chloride ...
متن کاملBis[N-(2-hydroxybenzyl)adamantan-1-aminium] fluoride tetrafluoroborate monohydrate
In the title compound, 2C(17)H(24)NO(+)·BF(4) (-)·F(-)·H(2)O, the asymmetric unit contains two N-(2-hy-droxy-benz-yl)adamantan-1-aminium cations, one BF(4) (-) anion, one F(-) anion and one water mol-ecule. Both amine N atoms are protonated. The hy-droxy O atoms, amino N atoms and water O atom are involved in inter-molecular O-H⋯O, O-H⋯F, N-H⋯O and N-H⋯F hydrogen bonding.
متن کاملN-Methyl-l-leucyl-l-leucine hydrochloride monohydrate
In the title compound C(13)H(27)N(2)O(3) (+)·Cl(-)·H(2)O, obtained by deprotecting the amino and carboxyl groups of an inter-mediate in the synthesis of the cyclic penta-peptide Galaxamide, a number of hydrogen-bonding inter-actions occur including aminium N-H⋯Cl, amide-carboxyl N-H⋯O, water O-H⋯Cl and carbox-yl-water O-H⋯O associations. The aminium N-H⋯Cl⋯H-N bridging extensions give rise to z...
