A variety of O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, as well as C-H⋯π inter-actions, are present in the crystal structure. Two water O atoms are each disordered over two positions; for both the site occupany factors are ca 0.66 and 0.34. ...[more]

Hexa-kis-(propyl-ammonium) benzene-1,2,4,5-tetra-carboxyl-ate 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate tetra-hydrate.

Project description:The title organic salt, 6C(3)H(10)N(+)·C(10)H(2)O(8) (4-)·C(10)H(4)O(8) (2-)·4H(2)O, contains seven independent entities in the asymmetric unit which comprises three propyl-ammonium cations, two water mol-ecules, half a 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate dianion (H(2)btc(2-)) and half a benzene-1,2,4,5-tetra-carboxyl-ate tetra-anion (btc(4-)), the latter two anions being located about centres of inversion. One of the water mol-ecules is disordered over two positions in a 0.55 (2):0.45 (2) ratio. The combination of mol-ecular ions and water mol-ecules results in an extensive and complex three-dimensional network of hydrogen bonds, the network being made up of nine unique N-H⋯O inter-actions between the ammonium cations and the anions, as well as four unique O-H⋯O inter-actions between the water mol-ecules and the anions.

Project description:In the crystal of the title hydrated molecular salt, 2C(3)H(12)N(2) (2+)·C(10)H(2)O(8) (4-)·2H(2)O, the packing is stabilized by extensive N-H⋯O and O-H⋯O hydrogen-bonding inter-actions involving all three species, forming a supra-molecular three-dimensional structure.

Tetra-imidazolium piperazinediium bis-(benzene-1,3,5-tricarboxyl-ate) dihydrate.

Project description:During the crystallization of the title compound, 4C(3)H(5)N(2) (+)·C(4)H(12)N(2) (+)·2C(9)H(3)O(6) (3-)·2H(2)O, the acidic protons were transferred to the imidazole and piperazine N atoms, forming the final 4:1:2:2 hydrated mixed salt. The mean planes of the three carboxyl-ate groups in the anion are twisted with respect to the the central benzene ring, making dihedral angles of 13.5?(1), 14.5?(1) and 16.9?(1)°. In the crystal, the component ions are linked into a three-dimensional network by a combination of inter-molecular N-H?O, O-H?O and weak C-H?O hydrogen bonds. Further stabilization is provided by ?-? stacking inter-actions with centroid-centroid distances of 3.393?(2)?Å and weak C=O?? inter-actions [O-centroid = 3.363?(2)?Å].

Poly[[hexa-μ-aqua-diaqua-bis-(μ₄-dihydrogen benzene-1,2,4,5-tetra-carboxyl-ato)magnesiumdisodium] dihydrate].

Project description:The asymmetric unit of the title compound, {[MgNa₂(C₁₀H₄O₈)₂(H₂O)₈]·2H₂O}(n), contains one octa-hedrally coordin-ated Mg(II) atom (site symmetry 2/m), one octahedrally coordinated Na(I) atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligand, the second half of the ligand being generated by a twofold rotation axis. The basic framework of the title compound features infinite (-Na-Na-Mg-)(n) chains along [10-1] with the metal cations bridged by the coordinating water molecules. The chains are isolated from each other by μ₄-bridging btec ligands, which form inter-molecular O-H⋯O hydrogen bonds to uncoordinated water mol-ecules and the coordinated water mol-ecules of a neighbouring chain. In each btec ligand, there are also intramolecular O-H⋯O hydrogen bonds.

Piperazinediium bis-(2-carboxy-pyridine-3-carboxyl-ate).

Project description:The asymmetric unit of the title salt, C(4)H(12)N(2) (2+)·2C(7)H(4)NO(4) (-) or pipzH(2) (2+)·2(py-2,3-dcH(-)), prepared by a reaction between pyridine-2,3-dicarboxylic acid (py-2,3-dcH(2)) and piperazine (pipz), contains a monoanion and half of a centrosymmetric dication. The anionic fragment individually has two intra-molecular hydrogen bonds, an almost linear O-H⋯O bond between two carboxyl-ate groups and a C-H⋯O bond between the aromatic ring and carboxyl-ate group. Other O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds are responsible for three-dimensional expansion of the structure.

?-Benzene-1,2,4,5-tetra-carboxyl-ato-?O,O:O,O-bis-[diaqua(phen-an-thro-line-?N,N')nickel(II)] 0.67-hydrate.

Project description:The asymmetric unit of the title compound, [Ni(2)(C(10)H(2)O(8))(C(12)H(8)N(2))(2)(H(2)O)(4)]·0.67H(2)O, contains one complete binuclear complex and one half-mol-ecule, the latter being completed by crystallographic inversion symmetry, and 0.67 of a solvent water molecule. Each Ni(2+) cation is coordinated by a 1,10-phenanthroline ligand, a bidentate benzene-1,2,4,5-tetra-carboxyl-ate (btec) tetra-anion and two water mol-ecules to generate a distorted cis-NiN(2)O(4) octa-hedral coordination geometry. The btec species bridges the metal ions. In the crystal, the clusters and uncoordinated water mol-ecules are linked by O-H?O hydrogen bonds and ?-? inter-actions [shortest centroid-centroid separation = 3.596?(2)?Å] to form a three-dimensional network.

In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

Bis[?-1,2-bis-(1H-imidazol-1-ylmeth-yl)benzene-?N:N]disilver(I) bis-(4-carb-oxy-naphthalene-1-carboxyl-ate) tetra-hydrate.

Project description:In the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(12)H(7)O(4))(2)·4H(2)O, the dinuclear dication has crystallographically imposed inversion symmetry. Each Ag(I) ion is bicoordinated in a slightly distorted linear coordination geometry by the N atoms of two ligands, resulting in the formation of a 22-membered metallamacrocycle. In the dication, ?-? inter-actions are observed between the imidazole rings, with centroid-centroid distances of 3.528?(3)?Å and dihedral angles of 9.92?(9)°. The crystal structure is stabilized by inter-molecular O-H?O hydrogen bonds and ?-? inter-actions involving the benzene rings of adjacent dications, with centroid-centroid distances of 3.651?(2)?Å.

Poly[(μ-benzene-1,2,4,5-tetra-carboxyl-ato)tetra-silver(I)].

Project description:In the centrosymmetric title compound, [Ag(4)(C(10)H(2)O(8))](n), the benzene ring has irregular bond lengths but remains planar (r.m.s. deviation 0.0002 Å). The Ag-O bond lengths are in the range 2.153 (3)-2.615 (4) Å. The carboxyl-ate groups are oriented at dihedral angles of 26.4 (5) and 74.9 (4)° to the benzene ring. The coordination behaviour of each carboxyl-ate O atom is different: in one carboxylate, the O atoms are coordinated to a single and two Ag atoms; in the other carboxylate, the O atoms are coordinated to two and three Ag atoms. Non-classical inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure. The title compound forms a three-dimensional polymeric network due to the coordination of the Ag atoms.
