In the title compound, [Mg(C3H3N2)4(H2O)2]Cl2, the Mg(II) cation lies on a crystallographic inversion centre and is coordinated by two water mol-ecules and four N-atom donors from monodentate imidazole ligands, giving a slightly distorted octa-hedral stereochemistry. In the crystal, water O-H⋯Cl and imidazole N-H⋯Cl hydrogen bonds give rise to a three-dimensional structure.

Medetomidine is a chiral imidazole derivate whose dextroenantiomer is pharmacologically active. The major metabolic pathway of dexmedetomidine [(+)-4-(S)-[1-(2,3-dimethylphenyl)ethyl]-1H-imidazole] in humans is N-glucuronidation at the imidazolate nitrogens. We have purified the N3- and N1-glucuronides of dexmedetomidine, termed DG1 and DG2, respectively, according to their elution order in liq...

The asymmetric unit of the title compound, [ZnCl(2)(C(14)H(14)N(4))](n), contains a Zn(II) ion situated on a twofold rotation axis and one-half of a 1-{4-[(1H-imidazol-1-yl)meth-yl]benz-yl}-1H-imidazole (L) ligand with the benzene ring situated on an inversion center. The Zn(II) ion is coordinated by two chloride anions and two N atoms from two L ligands in a distorted tetra-hedral geometry. Th...

In the title complex, [Mn(SO(4))(C(10)H(9)N(5))(H(2)O)(4)]·2H(2)O, the Mn(2+) cation is six-coordinated by one N atom from a 1-[(1H-1,2,3-benzotriazol-1-yl)meth-yl]-1H-imidazole ligand and five O atoms from one monodentate sulfate ligand and four water mol-ecules in a distorted octa-hedral geometry. In the crystal, adjacent mol-ecules are linked through O-H⋯O and O-H⋯N hydrogen bonds into a thr...
