The multitopic ligand O,O'-bisnicotinic acid tetraethylene glycol, L, was designed for the coordination of two distinct types of metal ions. In this work, we describe how the O-donor part of L is used to coordinate to alkaline earth metal ions and that the N-donor atoms of L bind to group 11 elements. This makes L a suitable ligand for the combination of both metal ion types within the same com...

The title compound, [Fe(C(5)H(5))(C(11)H(9)O)], is of inter-est as a precursor to the synthesis of cheap ferrocene-based liquid crystals. The -OH substituent only results in weak C-H⋯O weak inter-actions between one of cyclo-penta-dienyl (Cp) ring H atoms and the O atom of a neighbouring mol-ecule with a distance of 3.308 (3) Å between the donor and acceptor atoms. The inter-planar angle betwee...

The coordination chemistry of germanium covers quite bulk fields, as shown by a survey covering the crystallographic and structural data of over two hundred examples. About ten percent of those complexes exist as distortion isomers and are summarised. These are discussed in terms of the coordination around the germanium(I), germanium(II) and germanium(IV) atoms, and correlations are drawn betwe...

In the title compound, [Zn(NCS)(2)(C(10)H(15)N(3))], the Zn atom is five-coordinated by the three N-donor atoms of the Schiff base ligand and by two N atoms from two thio-cyanate anions, forming a distorted ZnN(5) trigonal-bipyramidal coordination geometry for the metal ion. The side chain of the ligand is disordered over two sets of sites in a 0.655 (12):0.345 (12) ratio. In the crystal, mol-e...

In the title complex, [Ag(ClO(4))(CH(3)OH)(C(18)H(15)P)(2)], the angles around the central Ag(+) ion indicate that it is in a distorted tetrahedral coordination. The coordination sphere of silver is formed by two P atoms of two triphenyl-phosphine ligands, one O atom of a perchlorate anion and one O atom of a methanol mol-ecule. The crystal structure is stablized by a bifurcated inter-molecular...

In the title compound, [Pd(C6H4F)I(C6H16N2)], the Pd(II) atom is coordinated by two N atoms from the N,N,N',N'-tetra-methyl-ethylenedi-amine ligand, a C atom of the 4-fluoro-phenyl group and an iodide ligand in a distorted square-planar geometry, with an average deviation from the least-squares plane through the ligand donor atoms of 0.0159 (2) Å. The angles about the Pd(II) atom range from 83....

The Zn(II) ion in the title complex, [Zn(NCS)(2)(C(7)H(6)N(2)S)(2)], is tetra-hedrally coordinated within an N(4) donor set defined by two N atoms of two terminal isothio-cyanate ligands and by two heterocyclic N atoms of two different 2-amino-benzothia-zole ligands. This arrangement is stabilized by intra-molecular N-H⋯N hydrogen bonds. In the crystal structure, mol-ecules are linked through N...

Surface reactions with oxygen are a fundamental cause of the degradation of phosphorene. Using first-principles calculations, we show that for each oxygen atom adsorbed onto phosphorene there is an energy release of about 2 eV. Although the most stable oxygen adsorbed forms are electrically inactive and lead only to minor distortions of the lattice, there are low energy metastable forms which i...

In the title complex, [Cu(C(20)H(13)BrN(4))(C(18)H(15)P)(2)]BF(4)·0.5CH(2)Cl(2), the copper(I) cation adopts a distorted tetra-hedral arrangement, coordinated by two triphenyl-phosphine ligands and two N atoms of the potentially tridentate terpyridine ligand. One half-mol-ecule of dichloro-methane crystallizes with the complex. The chlorine atoms are disordered over two sites with occupancies f...

(H3tdmba, Fig. 1), is a tripodal quadridentate ligand having one tertiary amine-N and three phenolate-O donor atoms. Recently, we have reported the solvent extractive mutual separation of the Group 13 metals (aluminum, gallium and indium) using the above ligand, which showed high extraction selectivity of Ga3+ to Al3+ and In3+.1 It is of interest and significant to study the crystal structure o...
