The Mg centre in the title compound, [MgBr(2)(C(2)H(7)N)(3)], is penta-coordinated in a trigonal-bipyramidal mode with the two Br atoms in axial positions and the N atoms of the dimethyl-amine ligands in equatorial positions. The Mg(II) centre is located on a crystallographic twofold rotation axis. The crystal structure is stabilized by N-H⋯Br hydrogen bonds. The N atom and H atoms of one dimet...

The crystal structure of the title compound, [Cd(C(29)H(29)N(5))(2)](C(6)H(2)N(3)O(7))(2), consists of Cd(II) complex cations and picrate anions. In the complex cation, the Cd(II) ion is chelated by two bis-(1-allyl-benzimidazol-2-ylmeth-yl)benzyl-amine (babb) ligands in a distorted octa-hedral geometry. Extensive C-H⋯O hydrogen bonding occurs between cations and anions in the crystal structure.

By means of a mixed-ligand strategy, a novel bi-functional metal-organic framework, [H2N(CH3)2]·Zn(NDC)(atz)·H2O (NDC = 2,6-naphthalenedicarboxylic acid, Hatz = 1H-tetrazol-5-amine), was synthesized, which displays a three-dimensional two-fold interpenetrated framework. Owing to the introduction of two different functional organic ligands, this complex exhibits bi-functional properties, i.e., s...

A photolabile ruthenium-based complex, [Ru(bpy)2 (4AMP)2 ](PF6 )2 , (4AMP=4-(aminomethyl)pyridine) is incorporated into polyurea organo- and hydrogels via the reactive amine moieties on the photocleavable 4AMP ligands. While showing long-term stability in the dark, cleavage of the pyridine-ruthenium bond upon irradiation with visible or near-infrared irradiation (in a two-photon process) leads ...

One of the significant on-going challenges in chemistry is the specific and convenient detection of compounds of interest in the environment. Detection of volatile organic compounds (VOCs) via chemical ‘‘sniffing’’ requires an interaction between the VOC and a detector substrate, resulting in a measurable change. Crystal inclusion of VOCs into various d and d metal complexes has been found to a...

The crystal structures of the building block tetra-methyl-ammonium (2,2'-bi-pyridine-κ(2) N,N')tetra-cyanidoferrate(III) trihydrate, [N(CH3)4][Fe(CN)4(C10H8N2)]·3H2O, (I), and a new two-dimensional cyanide-bridged bimetallic coordination polymer, poly[[(2,2'-bi-pyridine-κ(2) N,N')di-μ2-cyanido-dicyanido(μ-ethyl-enedi-amine-κ(2) N:N')(ethyl-enedi-amine-κ(2) N,N')cadmium(II)iron(II)] monohydrate]...

The title compound, [Ti(C5H5)2(C9H11F12NO4P2)], is a four-membered titanacycle obtained from the reaction of Cp2Ti(η(2)-Me3SiC2SiMe3) and CH3N[P(OCH2CF3)2]2 {N,N-bis-[bis-(tri-fluoro-eth-oxy)phosphan-yl]methyl-amine, tfepma}. The Ti(II) atom is coordinated by two cyclo-penta-dienyl (Cp) ligands and the chelating tfepma ligand in a strongly distorted tetra-hedral geometry. The mol-ecule is locat...

Coinage metal cyanides (MCN) form photoluminescent 1D coordination polymers. The decoration of these chains with amine and phosphine ligands shifts the wavelength for photoluminescence into the visible region. Density-functional theory (DFT) and time-dependent DFT (TD-DFT) calculations of zigzag and helical models of decorated chains are used to show that the transitions that contribute to the ...

The benzene-o-dithiol/pyridylimine (S-S)/(N-N) ligand H2-7, representing the first example of a new type of bis(bidentate) heterodonor ligands with a mixed donor set, has been synthesized by Schiff base condensation of pyridine-2-carbaldehyde with an amine-substituted benzene-o-dithiol moiety. Bis(cyclopentadienyl)titanium dichloride reacts selectively at the S-S donor group of H2-7 to yield co...

The Pd(II) atom of the title salt, [Pd(C(10)H(9)N(3))(2)](NCS)(2), lies on a center of inversion and exists in a square-planar environment defined by the four pyridine N atoms derived from the two chelating di-2-pyridyl-amine (dpa) ligands. The chelate ring displays a boat conformation with a dihedral angle between the pyridine rings of 43.0 (1)°. Adjacent thio-cyanate ions are linked to the ca...
