Hydrogen Bonded

Crystalline 3D hydrogen bonded frameworks are assembled in water from tetrahedral tetraamidinium cations and antielectrostatically hydrogen bonded bicarbonate dimers. The framework forms in water, and represents a clear demonstration of the potency of these anti-Coulombic hydrogen bonds. Gentle heating of the framework (50 °C) releases CO2 and water to give the neutral tetraamidine compound.

The title isotypic complexes, bis[μ-5,6-bis(pyridin-2-yl)pyrazine-2,3-dicarboxylato]-κ4N1,O2,N6:O3;κ4O3:N1,O2,N6-bis[diaquamanganese(II)] tetrahydrate, [Mn2(C16H8N4O4)2(H2O)4]·4H2O, (I), and bis[μ-5,6-bis(pyridin-2-yl)pyrazine-2,3-dicarboxylato]-κ4N1,O2,N6:O3;κ4O3:N1,O2,N6-bis[diaquairon(II)] tetrahydrate, [Fe2(C16H8N4O4)2(H2O)4]·4H2O, (II), are, respectively, the manganese(II) and iron(II) complexes of the ligand 5,6-bis(pyridin-2-yl)-pyrazine-2,3-dicarboxylic acid. The complete molecule of each complex is generated by inversion symmetry. Each metal ion is coordinated by a pyrazine N atom, a pyridine N atom, two carboxylate O atoms, one of which is bridging, and two water O atoms. The metal atoms haveMN2O4coordination geometries and the complexes have a cage-like structure. In the crystals of both compounds, the complexes are linked by O—H...O and O—H...N hydrogen bonds involving the coordinating water molecules, forming chains along [100]. These chains are linked by O—H...O hydrogen bonds involving the non-coordinating water molecules, forming layers parallel to (011). The layers are linked by pairs of C—H...O hydrogen bonds and offset π–π interactions, so forming a hydrogen-bonded three-dimensional framework.

Two complexes, [Zn(Him)2(mpa)] (1) and [Zn(Him)2(tpa)]·H2O (2) (Him = imidazole, mpa = m-phthalate, and tpa = terephthalate), have been prepared and structurally characterized, revealing two different three-dimensional hydrogen-bonded molecular architectures. Each features [Zn(Him)2(dicarboxylate)] zigzag polymeric chains and intermolecular N–H…O hydrogen bonds between the uncoordinated Him nitrogen atoms and carboxylate oxygen atoms that are similar to the carboxylate–histidine–zinc triad systems in zinc(II) enzymes. The lattice water molecules in complex (2) play a critical role in the formation of a three-dimensional hydrogen-bonded molecular architecture.

Thymine crystallizes from 50% hydrogen peroxide to give the title hydrogen peroxide water solvate, C5H6N2O2·0.55H2O2·0.45H2O. The disordered peroxide and water molecules occupy the same positions. Thymine molecules are linked together by N—H...O hydrogen bonds forming chains parallel to the ac diagonal. Hydrogen peroxide molecules are combined by O—H...O hydrogen bonds to give chains parallel to the c axis. Both kinds of chains are organized in a three-dimensional hydrogen-bonded network.

Organic Framework

A novel CdIImetal–organic framework, [Cd(C3H2O4)(NH3)]n, was synthesized by liquid diffusion conducted in the presence of ammonia. The CdIIatom has seven-coordinate O6N pentagonal–bipyramidal geometry. Six CdIIcenters are joined by six malonate ligands to form anS6-symmetric [Cd6(malonate)6] metallomacrocycle, which is further extended through a side-on chelating malonate ligand to form a three-dimensional network. Topologically, each CdIIcenter is connected to four others to yield an infinite three-periodic four-coordinated SOD (sodalite) network with point symbol {42·64}. The overall network structure in the crystal is maintained and stabilized by the presence of N—H...O hydrogen bonds.

The molecules of (I) are linked by O—H...O and O—H...N hydrogen bonds to form a cyclic centrosymmetricR44(16) tetramer. The molecules of (II) are linked by O—H...O hydrogen bonds to form aC22(4) chain and these chains are weakly linked by a single C—H...π(thienyl) interaction to form a three-dimensional array. Comparisons are made with some related compounds.
