The CadmiumII Isophthalicacid Benzimidazole complex [Cd2(C8H4O4)2 (C7H6N2)4(H2O)3], Triqua-bis (isophthalicacidato-O,O')-tetra (benzimidazole) bis (CadmiumII),the CdII atom is coordinated by two isophthalicacid anions and two benzimidazole and one water molecule in a distorted octahedral configuration with six-coordinations geometry. And one isophthalicacid ligand chelates to the CdII atom through its one carboxylic O atoms, but the other isophthalicacid ligand chelates to the CdII atom through its two carboxylic O atoms. The same as another CdII atom. So we get a Binuclear CdII metal complexe. The fact clearly suggests not so much significant contribution from the electrostatic interaction in the Cd-O bonding in bidentate Binuclear CdII metal complexes as we gotten in mononuclear MnII metal complexes. Adjacent complex link to each other via hydrogen bonds forming the three-dimensional supramolecular structure.

The tin(IV) atom in the complex anion of the title salt, (C4H7N2)[Sn(C2O4)Cl3(H2O)], is in a distorted octahedral coordination environment defined by three chlorido ligands, an oxygen atom from a water molecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N—H...O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex [Sn(H2O)Cl3(C2O4)]−anion. Neighbouring stannate(IV) anions are linked through O—H...O hydrogen bonds involving the water molecule and the two non-coordinating oxalate oxygen atoms. In combination with additional N—H...Cl hydrogen bonds between cations and anions, a three-dimensional network is spanned.

The asymmetric unit of the title compound, NH4+·C11H14N6O7P−·0.5H2O, contains one 3′-azido-3′-deoxythymidine-5′aminocarbonylphosphonate (ACP–AZT) anion, half of an NH4+cation lying on a twofold rotation axis and in another position, occupied with equal probabilities of 0.5, an NH4+cation and a water molecule. The amide group of the ACP–AZT anion is disordered (occupancy ratio 0.5:0.5), with one part forming an N—H...O (involving C=O...H4N+) hydrogen bond and the other an O—H...N (involving C—NH2...OH2) hydrogen bond with the components of the split NH4+/H2O position. The pseudorotation parameters of ACP–AZT set it apart from previously studied AZT and thymidine. In the crystal, the various components are linked by N—H...O, O—H...O, N—H...N, C—H...O and C—H...N hydrogen bonds, forming a three-dimensional framework.

In the structure of the complex salt formed from the reaction of manganese(II) acetate with (4-aminophenyl)arsonic acid (p-arsanilic acid), [Mn(H2O)6](C6H7AsNO3)2·4H2O, the centrosymmetric Mn(H2O)6coordination polyhedron has slightly distorted octahedral stereochemistry, with the two hydrogen (4-aminophenyl)arsonate anions and the four water molecules of solvation related by inversion. Extensive O—H...O, O—H...N and N—H...O hydrogen bonds link all species, giving an overall three-dimensional supramolecular structure, which also has weak π–π ring interactions [minimum ring-centroid separation = 3.7304 (15) Å]. The structure is isotypic with that of the Mg salt.
