(η-All-yl)bromido(1-phenyl-1H-imidazole-κN)palladium(II).

ABSTRACT: The title compound, [PdBr(C(3)H(5))(C(9)H(8)N(2))], was synthesized by the reaction of the allyl-palladium(II) bromide dimer and 1-phenyl-1H-imidazole. The Pd atom is coordinated by one allyl group [in η(3) mode, the central CH group of the allyl group is disordered over two sets of sites in a 0.668 (5):0.332 (5) ratio], one bromide anion and a 1-phenyl-1H-imidazole ligand. Intra-molecular face-to-face π-π stacking inter-actions occur between adjacent phenyl or imidazole groups, with centroid-centroid distances in the range 3.877 (1)-3.6596 (6) Å, forming a supra-molecular chain along [100].

Hexa-kis-(1H-imidazole-κN)iron(II) sulfate-1H-imidazole (1/2).

Project description:The asymmetric unit of the title compound, [Fe(C(3)H(4)N(2))(6)]SO(4)·2C(3)H(4)N(2), contains two complex cations, two sulfate anions and four imidazole mol-ecules. In both cations, the Fe(II) atom is coordinated by six monodentate imidazole ligands and exhibits a slightly distorted octa-hedral coordination geometry. The Fe-N distances [2.184 (4)-2.218 (4) Å] point to a high-spin state of the Fe(2+) ions. N-H⋯O hydrogen bonds between the ionic components generate a three-dimensional framework containing corrugated channels along [001], which are filled by N-H⋯N hydrogen-bonded imidazole chains.

Project description:In the crystal structure of the title compound, [Mn(C(3)H(4)N(2))(6)][Mn(C(3)H(4)N(2))(3)(H(2)O)(3)](C(12)H(6)O(4))(2), there are uncoordinated naphthalene-dicarboxyl-ate dianions and two kinds of Mn(II) complex cations, both assuming a distorted octa-hedral geometry. One Mn(II) cation is located on an inversion center and is coordinated by six imidazole mol-ecules, while the other Mn(II) cation is located on a twofold rotation axis and is coordinated by three water mol-ecules and three imidazole units. The naphthalene-dicarboxyl-ate dianions are linked to both Mn(II) complex cations via O-H⋯O and N-H⋯O hydrogen bonding, but no π-π stacking is observed between aromatic rings in the crystal structure.

Weak π-π inter-actions, both intra- and inter-molecular [shortest inter-centroid distance = 4.598 (5) Å], are also noted in the three-dimensional architecture.
