In the title hydrated salt, C(5)H(7)N(2) (+)·C(6)H(9)O(4) (-)·H(2)O, the carb-oxy H atom is disordered over two positions with equal occupancy. In the crystal, O atoms of the 5-carb-oxy-penta-noate anion link the 4-amino-pyridinium cations and water mol-ecules into a three-dimensional network via

The asymmetric unit of the title mol-ecular salt (systematic name: 4-amino-anilinium 5-carb-oxy-penta-noate), C6H9N2+·C6H9O4-, consists of half a 4-amino-benzenaminium cation (4-ABA) and half a 5-carb-oxy-penta-noate anion (5-CP); the other half of each ion is generated by inversion symmetry.

A novel carbohydrate-rich sialoglycopeptide of apparent molecular mass approximately 6 kDa was isolated from the fertilized eggs of Fundulus heteroclitus (euryhaline killi fish). This glycopeptide is a member of the L-hyosophorin family, characterized by its high content of carbohydrate (80-90% by

New glycoproteins of 100-120 kDa were isolated from the unfertilized eggs of flounder, Paralichthys olivaceus. Compositionally indistinguishable glycopeptides of 6 kDa were also purified from the activated or fertilized eggs. These high and low molecular mass glycoproteins are characterized by high

In the title compound, C21H21NO5, obtained from a Morita-Baylis-Hillman adduct, the hydrogenated five-membered ring adopts a shallow envelope conformation, with the C atom bearing the carb-oxy-lic acid substituent deviating by 0.237 (1) Å from the mean plane of the other four atoms (r.m.s. deviation

The title compound, C40H22Cl2O4, was formed by a Michael-Aldol domino reaction sequence, which coupled acenaphthene-quinone with 4-chloro-aceto-phenone in the presence of KOH in methanol. The dihedral angles between the central cyclo-penta-[a]ace-naphthyl-ene fused-ring system (r.m.s. deviation =

In the title compound, [Pb(2)(C(9)H(4)O(6))(2)(C(19)H(12)N(4))(2)], the Pb(II) atom is five-coordinated by two N atoms from a chelating 2-phenyl-1H-1,3,7,8-tetra-aza-cyclo-penta-[l]phenanthrene (L) ligand and three O atoms from two Hbtc ligands (H(3)btc is benzene-1,3,5-tricarb-oxy-lic acid),

The central Sn(IV) atom of the penta-nuclear title complex, {[Sn(CH(3))(3)](3)O(2)C(CH(2))PO(3)[Sn(CH(3))(3)(H(2)O)](2)HO(2)C(CH(2))PO(3)}, is located on a twofold rotation axis; due to symmetry, the H atom of the carboxyl group of the anion is disordered with a site occupancy of 0.5. The central

The structure of the title compound, [Li(C(6)H(3)N(2)O(4))(2)(H(5)O(2))], is composed of centrosymmetric monomers in which an Li(I) ion is chelated by two N,O-bonding groups donated by two ligands. The Li(I) ion and both ligand mol-ecules are coplanar [r.m.s. deviation 0.0047 (2) Å] and water O

ABE fermentation by Clostridium beijerinckii of steam-exploded and ozonated wheat straw hydrolysates was investigated. In steam-exploded hydrolysates, highest yields of 0.40 g/g ABE yield and 127.71 g ABE/kg wheat straw were achieved when the whole slurry from the pretreatment was used. In ozonated

In the title compound, [Ce(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(5)]·4H(2)O, the Ce(3+) ion is nine-coordinated by two O atoms and two N atoms from one single and from one double deprotonated pyridine-2,5-dicarboxyl-ate ligand and five water mol-ecules in a distorted monocapped square-anti-prismatic

The title compound, C(19)H(23)F(2)N(4)O(3) (+)·0.5SO(4) (2-)·2.5H(2)O, an anti-bacterial fluoro-quinolone, crystallized as a racemic twin (major twin component = 0.633) in the chiral space group P1. The asymmetric unit contains two sparfloxacinium cations, one sulfate anion and five mol-ecules of

In the crystal structure of the title compound, C(12)H(26)N(2)O(4) (2+)·2(Br(0.085)Cl(0.915))(-)·4C(5)H(9)OH, the complete cation is generated by crystallographic twofold symmetry. Contamination of the chloride counter-anion with bromide occured during the preparation, due to the use of

The title compound [Mn6(C7H4NO3)5(C3H5O2)2(C4H6N2)4.17(C3H7NO)1.83]·0.24C3H7NO·1.36CH3OH or Mn(II)(C3H5O2)2[15-MCMn(III)N(shi)-5](Me-Im)4.17(DMF)1.83·0.24DMF·1.36MeOH (where MC is metallacrown, shi(3-) is salicyl-hydroximate, Me-Im is 1-methyl-imidazole, DMF is N,N-di-methyl-formamide, and MeOH is

Carbohydrate-based phosphoranes were synthesized by reacting the appropriate diphenol with phosphorus trichloride followed by the addition of chloralose to form 1 and by the addition of isopropylidene-D-glucofuranose to form 2 and 3. Phosphorane 4 was obtained by reacting
