Pentakis(l-prolinium) dodecatungstoborate trihydrate
The title polyoxometalate-based organic-inorganic hybrid compound, (C(5)H(10)NO(2))(5)[BW(12)O(40)]·3H(2)O, consists of one α-Keggin-type [BW(12)O(40)](5-) polyoxoanion, five crystallographically independent l-prolinium cations and three uncoordin-ated water mol-ecules. The polyoxoanion shows characteristic features with respect to bond lengths and angles. Several N-H⋯O and O-H⋯O hydrogen bonds...
متن کاملBenzimidazolium 3,5-dicarboxybenzoate trihydrate
Cocrystallization of benzimidazole with benzene 1,3,5-tricarb-oxy-lic acid in slightly basic medium afforded the title compound, C(7)H(7)N(2) (+)·C(9)H(5)O(6) (-)·3H(2)O, in which one of the imidazole N atom is protonated and one carb-oxy-lic group of aromatic acid is deprotonated. In the crystal structure, inter-molecular N-H⋯O hydrogen-bonding connects the two organic components into dimers, ...
متن کاملTetraethylammonium bicarbonate trihydrate
In the title compound, C(8)H(20)N(+)·CHO(3) (-)·3H(2)O, the bicarbon-ate anion, which has a small mean deviation from the plane of 0.0014 Å, fully utilises its three O and one H atom to form various O-H⋯O hydrogen bonds with the three water mol-ecules in the asymmetric unit, generating a hydrogen-bonded layer, which extends along (10[Formula: see text]). The tetra-ethyl-ammonium cations, as the...
متن کاملHexaaquagallium(III) trinitrate trihydrate
The title compound, [Ga(H(2)O)(6)](NO(3))(3)·3H(2)O, is isostructural to other known M(III) nitrate hydrates (M = Al, Cr, Fe). The structure contains two distinct octa-hedral Ga(OH(2))(6) units (each of symmetry) which are involved in inter-molecular hydrogen bonding with the three nitrate anions and three water mol-ecules within the asymmetric unit.
متن کاملDipotassium disulfanilamidate trihydrate
The asymmetric unit of the title compound, 2K(+)·2C(6)H(7)N(2)O(2)S(-)·3H(2)O, consists of two potassium cations located on mirror planes, one sulfanilamidate anion in a general position and one and a half mol-ecules of water, one of which is also located on a mirror plane. One potassium cation is seven-coordinated by six sulfonyl O atoms and one water mol-ecule, whereas the other is surrounded...
