AI Article Synopsis
- The complex, titled {[Co(2)(C(9)H(4)N(2)O(4))(2)(H(2)O)(4)]·3H(2)O}(n), was synthesized using hydrothermal methods.
- The Co(II) ion is coordinated in a distorted octahedral geometry with two water molecules and three 1H-benzimidazole-5,6-dicarboxylate ligands, forming a two-dimensional structure.
- Intermolecular hydrogen bonds create a three-dimensional network, with one solvent water molecule positioned on a twofold rotation axis.
Article Abstract
The title complex, {[Co(2)(C(9)H(4)N(2)O(4))(2)(H(2)O)(4)]·3H(2)O}(n), was synthesized hydro-thermally. The unique Co(II) ion is coordin-ated in a distorted octa-hedral coordination environment by two water mol-ecules and three symmetry-related 1H-benzimid-azole-5,6-dicarboxyl-ate (Hbidc) ligands. The Hbidc ligands coordinate via a bis-chelating and mono-chelating carboxyl-ate group and by an imidazole group N atom, bridging the Co(II) ions and forming an extended two-dimensional structure in the ab plane. In the crystal structure, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect complex and solvent water mol-ecules, forming a three-dimensional supermolecular network. One of the solvent water mol-ecules lies on a twofold rotation axis.

The title compound, a hydrate of 3,5-di-amino-1,2,4-triazole (DATA), CHN·HO, was synthesized in the presence of sodium perchlorate. The evaporation of HO from its aqueous solution resulted in anhydrous DATA, suggesting that sodium perchlorate was required to precipitate the DATA hydrate. The DATA hydrate crystallizes in the 2/ space group in the form of needle-shaped crystals with one DATA and one water mol-ecule in the asymmetric unit.

Lopinavir is a potent protease inhibitor that is used as a first-line pharmaceutical drug for the treatment of HIV. The multi-component solvated Lopinavir crystal, systematic name (2)--[(2,4,5)-5-[2-(2,6-di-methyl-phen-oxy)acetamido]-4-hy-droxy-1,6-di-phenyl-hexan-2-yl]-3-methyl-2-(2-oxo-1,3-diazinan-1-yl)butanamide-ethane-1,2-diol-water (8/3/7) 8CHNO·3CHO·7HO, was prepared using evaporative methods. The crystalline material obtained from this experimental synthesis was characterized and elucidated by single-crystal X-ray diffraction (SC-XRD).

The asymmetric unit of the title compound, [Co(CBrO)(CHN)(HO)] or [Co(Brbdc)(im)(HO)] , comprises half of Co ion, tetra-bromo-benzene-dicarboxylate (Brbdc), imidazole (im) and a water mol-ecule. The Co ion exhibits a six-coordinated octa-hedral geometry with two oxygen atoms of the Brbdc ligand, two oxygen atoms of the water mol-ecules, and two nitro-gen atoms of the im ligands. The carboxyl-ate group is nearly perpendicular to the benzene ring and shows monodentate coordination to the Co ion.
