synthesis of 2-phosphonobutane-1, 2, 4-tricarboxylic acid
2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...
متن کامل4-[(E)-2-Ferrocenylethenyl]-1,8-naphthalic anhydride
In the structure of the title compound, [Fe(C(5)H(5))(C(19)H(11)O(3))], the plane of the substituted ferrocene ring is tilted by 14.17 (6)° with respect to the mean plane through the naphthalene ring system. In the crystal structure, centrosymmetric dimers are formed through π-π inter-actions [centroid-centroid distance = 3.624 (2) Å] between the substituted ferrocene ring and the three fused r...
متن کامل2-Aminobenzoic acid–4-(pyridin-4-yldisulfanyl)pyridine (1/1)
The title 1:1 co-crystal, C(7)H(7)NO(2)·C(10)H(8)N(2)S(2), features a highly twisted 4-(pyridin-4-yldisulfan-yl)pyridine mol-ecule [dihedral angle between the pyridine rings = 89.06 (10)°]. A small twist is evident in the 2-amino-benzoic acid mol-ecule, with the C-C-C-O torsion angle being -7.7 (3)°. An N-H⋯O hydrogen bond occurs in the 2-amino-benzoic acid mol-ecule. In the crystal, mol-ecules...
متن کاملNaphthalene-1,4,5,8-tetracarboxylic acid 1,8-anhydride–4,4′-bipyridine (1/1)
The title compound, C(14)H(6)O(7)·C(10)H(8)N(2), has been hydro-thermally synthesized. Structural ananlysis indicates that the crystals are produced by cocrystallization of naphthalene-1,4,5,8-tetra-carboxylic acid 1,8-anhydride and 4,4'-bipyridine (bpy) mol-ecules. The crystal packing is stabilized by inter-molecular O-H⋯N and C-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centr...
متن کاملOxalic acid–pyridine-4-carbonitrile (1/2)
In the title compound, 2C(6)H(4)N(2)·C(2)H(2)O(4), the oxalic acid mol-ecule lies about an inversion center. The pyridine ring of the pyridine-4-carbonitrile mol-ecule is almost planar, the largest deviation from the least-squares plane being 0.006 (1) Å; the nitrile N atom deviates from this plane by 0.114 (1) Å. In the crystal, the oxalic acid mol-ecules and the pyridine-4-carbonitrile mol-ec...
