The title compound (C(5)H(14)NO)(4)[Cu(2)(CH(3)COO)(4)Cl(2)]Cl(2), consists of a pair of Cu(II) ions bridged by four acetate groups, resulting in a Cu(2)(CH(3)COO)(4) unit, four (3-hydroxy-prop-yl)dimethyl-ammonium cations (two crystallographically independent pairs) and two chloride anions. The Cu atoms at both termini are bonded to chloride anions. The latter are hydrogen bonded to one of the...

Direct excitation and {1H}13C-CPMAS NMR allowed detecting carbamate–ammonium ion pairs, carbamic acid bicarbonate species in amine-modified silica sorbents.

The crystal structure of the title compound, (C6H14N)3[Sn(C2O4)2Cl2]Cl·H2O, contains three cyclo-hexyl-ammonium cations, one stannate(IV) dianion, one isolated chloride anion and one lattice water mol-ecule. The cyclo-hexyl-ammonium cations adopt chair conformations. In the complex anion, two bidentate oxalate ligands and two chloride anions in cis positions coordinate octa-hedrally to the cent...

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 ...

The title compound, H(3)O(+)·C(4)H(10)NO(6)P(2) (-)·H(2)O, was obtained from the reaction of cyclo-propane-carbonitrile with PCl(3), followed by dropwise addition of water. The asymmetric unit comprises an oxonium cation, a zwitterionic monoanion containing a positively charged ammonium group and two negatively charged phospho-nic acid residues and a water mol-ecule of crystallization. The hydr...

The title compound, C(24)H(21)N(3)O, was prepared by the reaction of (Z)-2-(1H-indol-3-ylmethyl-ene)-1-aza-bicyclo-[2.2.2]octan-3-one with α-bromo-p-toluonitrile, under phase-transfer catalytic (PTC) conditions using triethyl-benzyl-ammonium chloride and 50% w/v aqueous NaOH solution in dichloro-methane. The crystal structure indicates the presence of a double bond with Z geometry connecting th...

The title compound, C(25)H(24)N(2)O(3) was prepared by the reaction of (Z)-2-(1H-indol-3-ylmethyl-ene)-1-aza-bicyclo-[2.2.2]octan-3-one with methyl p-(bromo-meth-yl)benzoate, under phase-transfer catalytic (PTC) conditions using triethyl-benzyl-ammonium chloride and 50% w/v aqueous NaOH solution in dichloro-methane. The crystal structure indicates the presence of a double bond with Z geometry c...

The synthesis of nanostructured anionic-surfactant-templated mesoporous silica (AMS) recently appeared as a new strategy for the formation of nanostructured silica based materials. This method is based on the use of anionic surfactants together with a co-structure-directing agent (CSDA), mostly a silylated ammonium precursor. The presence of this CSDA is necessary in order to create ionic inter...
