By taking advantage of how strain gradients affect spin energy levels, experiments provide a spatial map coherence times donor atoms in silicon---necessary information for many quantum-based applications.
The Sn(IV) atom in the title compound, [Sn(C(9)H(4)Cl(2)NO)(2)Cl(2)], is chelated by the substituted quinolin-8-olate anions in a distorted octa-hedral geometry. The N-donor atoms are in a cis alignment as are the Cl atoms; the O atoms are trans to each other.
nbo analysis, hybrid density functional theory (b3lyp/6-311+g**) and ab initio molecular orbital (hf/6-311+g**) based methods were used to study the anomeric effects (ae), electrostatic interactions, dipole-dipole interactions and steric repulsion effects on the conformational properties of 2-methoxy- (1), 2-methylthio- (2), 2-methylseleno- (3), 2-fluoro- (4), 2-chloro- (5) and 2-bromocyclohexa...
The key elements in the steady miniaturization process of cutting-edge semiconductor devices are the understanding and controlling of charge dynamics on the atomic scale. In detail, we address the study of charging processes of individual doping atoms and, especially, the interaction of those atoms with their surroundings. We use pulsed optical excitation in combination with scanning tunneling ...
Several PNP-type diphosphine ligands have been synthesised and characterised, featuring a single or double N-bridge between the P-donor atoms. PNP 1 2 containing diazaphospholane donors been...
In the crystal structure of the title compound, [Mn(C(12)H(6)O(4))(C(10)H(8)N(2))](n), the Mn atoms are each coordinated by four O atoms of naphthalene-1,4-dicarboxyl-ate anions and two N atoms of two symmetry-related 4,4'-bipyridine ligands within a strongly distorted octa-hedra. Two of the O atoms originate from one naphthalene-1,4-dicarboxyl-ate anion, whereas the remaining two O atoms deriv...
The asymmetric unit of the title compound, [Mo(C(14)H(12)NO)(2)O(2)], comprises half of the complex with the full mol-ecule generated by the application of twofold symmetry. The Mo(VI) atom is surrounded by two oxide O atoms and the two sets of N,O-donor atoms of the bidentate Schiff base ligands. The resulting N(2)O(4) donor set defines a distorted octa-hedral coordination geometry. Inter-mole...
In the title compound, [Co(NCS)(2)(C(16)H(16)N(4)O(2))](n), the octa-hedrally coordinated Co(II) ion lies on a crystallographic inversion center, with trans isothio-cyanate ligands. Pyridyl N-donor atoms and formyl O-donor atoms from exotetra-dentate bis-(4-pyridyl-carbon-yl)piperazine (4-bpfp) ligands link the Co(NCS)(2) units into a [Co(NCS)(2)(4-bpfp)](n) coordination polymer layer that is o...
The order and number of metal atoms in a Pd/Cu chain are controlled using variable donor ligand terminus coordinating anions, leading to different synergistic reactivity Ar–O bond formation with H 2 O alkyne activation.
