Several hypotheses to elucidate the linkage isomer preference of the thiocyanate (SCN(-)) ion have been offered. For complexes with small coordination numbers (i.e., 1 and 2) and groups 11 (Cu-triad) and 12 (Zn-triad) metals, different levels of theory and a variety of basis sets have been employed to study linkage isomerism. Similar results are obtained for all density functionals tested, pure...

An electrochemically bistable ruthenium polypyridyl complex was immobilised on platinum electrodes via amide condensation with an amine-terminated self-assembled thiol monolayer and underwent rapid electron transfer-induced linkage isomerism.

Density Functional theoretical calculations confirm the experimental observation that the low-temperature photolysis of (TPP)Fe(NO)(NO2) (as a KBr pellet) results in the generation of linkage isomers involving the axial NO and NO2 groups and suggest the possible formation of the double linkage isomer (TPP)Fe(ON)(ONO). The energy difference between the ground state (porphine)Fe(NO)(NO2) and the ...

BN Benzonitrile 2, a 1,2-dihydro-1,2-azaborine bearing an electron-withdrawing boron substituent was prepared and characterized, and its coordination chemistry investigated; reactivity studies revealed that BN benzonitrile 2 undergoes BCN-BNC linkage isomerism upon coordination to Cr(CO)(5).

In this research project, the nitrito nitro isomerization of [Co (NH3)5No2]F2 complex has been studied. Isomerization of this complex in the solid state follows a first order kinetics. The rate of isomerization at different temperatures was determined using a Fourier Transform Lnfrared Spectrophotometer. ? and ? are calculated at 298 K. The infrared, visible and ultraviolet spectra of th...

Four procyanidin trimers have been isolated and their structures unequivocally established as: epicatechin(4~+8)'epicatechin-(4~+8)-catechin (5); epicatechin-(4~-+6)-epicatechin-(4~-8)-catechin (6); epicatechin(4~8)-epicatechin-(4~6)-catechin (7); and epicatechin-(4~-8)-epicatechin-(4~-+8).epic8techin (13), The presence of the first three trimers in Pinus tBeds phloem. and the isolation of both...

Ruthenium polypyridyl complexes have seen extensive use in solar energy applications. One of the most efficient dye-sensitized solar cells produced to date employs the dye-sensitizer N719, a ruthenium polypyridyl thiocyanate complex. Thiocyanate complexes are typically present as an inseparable mixture of N-bound and S-bound linkage isomers. Here we report the synthesis of a new complex, [Ru(te...

Background: So-called heterotaxy, better called bodily isomerism, is associated with increased frequency of thrombocytosis and thromboembolic events in childhood. This is likely mediated by splenic dysfunction present with isomerism. Data for adults with isomerism is lacking with a paucity of data regarding thrombosis and isomerism. This study aimed to determine the risk of thrombocytosis and t...
