A 3D porous framework [Co3(μ2-OH)4(I)2]·2H2O (I = hypoxanthine) with two types of 1D channels possess excellent catalytic ability for the selective oxidation of cis-cyclooctene.

The use of two metal systems cis-Pt(NHC)(2)Me(2) and cis-Ir(NHC)(CO)(2)Cl help to highlight the flexibility of a series of cycloalkyl-substituted N-heterocyclic carbene ligands (ICy, ICy(7), ICy(8), ICy(12)). Bond dissociation enthalpies of several N-heterocyclic carbenes (NHCs) in cis-Pt(NHC)(2)Me(2) are estimated. Electronic and steric parameters of the ICy(n) ligands are quantified and discu...

Bromine has been added to cis,trans,trans-1,5,9-cyclododecatriene under various reaction conditions. All expected direct addition products have been isolated, and their structures have been determined by microanalysis, NMR and X-ray crystallography. Advanced NMR techniques were used to determine solution conformations of several of the compounds, enabling comparison with the solid-state conform...

In the title 1:2 adduct, [SnCl(4)(H(2)O)(2)]·2C(6)H(14)O(3), the Sn(IV) atom (site symmetry 2) adopts a cis-SnO(2)Cl(4) octa-hedral geometry. In the crystal structure, O-H⋯O hydrogen bonds lead to associations of one metal complex and two diglyme mol-ecules.

Of the bisurea compounds linked through trans- and cis-benzanilide spacers, the cis-amide derivatives were found to be effective in chloride transport, using which a stimuli-responsive mobile carrier was devised.

On-the-fly dynamics simulations were carried out using spin-flip time dependent density functional theory (SF-TDDFT) to examine the photoisomerization and photocyclization mechanisms of cis-stilbene following excitation to the ππ* state. A state tracking method was devised to follow the target state among nearly degenerate electronic states during the dynamics simulations. The steepest descent ...

Filamentous forms of Escherichia coli, induced by growth in the presence of cis-dichlorodiammineplatinum(II), contain amorphous inclusion aggregates, possibly ribosomal, with an affinity for uranium ion.

The asymmetric unit of the title distannoxane, [Sn(4)(C(4)H(9))(8)(C(3)H(4)N(3)S)(2)(CH(3)O)(2)O(2)], contains two mol-ecules, each of which lies about an individual center of inversion. The tetra-nuclear mol-ecule features a three-rung-staircase Sn(4)O(4) core in which two independent Sn(IV) atoms are bridged by the triazolide group. The negatively charged N atom of the triazolide group binds ...

Oppong and King present a clear and concise review of the current data regarding lobular carcinoma in situ (LCIS) and discuss the rationale behind the current management recommendations for this disease. It is interesting to note that in 2011 we are still debating the clinical management of LCIS despite these lesions having first been recognized in the early 1900s.[1] Recent advances in genomic...
