In the title complex mol-ecule, [Ti(C(10)H(15))(2)I], the paramagnetic Ti(III) atom is coordinated by two penta-methyl-cyclo-penta-dienyl (Cp*) ligands and one iodide ligand. The two Cp* ligands are in a staggered orientation. The coordination geometry at the titanium atom can be described as distorted trigonal-planar.
The title complex, dichlorido[N,N-di-methyl-2-(η(5)-tetra-methyl-cyclo-penta-dien-yl)acetamidinido-κN']titanium(IV), [Ti(C(13)H(20)N(2))Cl(2)], exhibits an unusual ansa-bridged conformation. The cyclo-penta-dienyl ring and the mean plane of the Ti-N=C-C-C fragment form a dihedral angle of 88.08 (11)°.
AimTimely vaccination is essential to achieve full potential of the especially in child population. Despite success increasing coverage India's universal immunization programme (UIP), timely remains a challenge. This study aims understand key socioeconomic correlates delay and guide by charting future course action.Subject & methodsThis was part review conducted four states namely Madhya Prades...
The prenatal abnormalities in patients with penta X syndrome appear late in pregnancy and are nonspecific. In contrast, the postnatal phenotype is well described although new findings are still revealed. Penta X syndrome is a result of successive nondisjunctions of the X chromosomes in both maternal meiotic divisions.
Reduced graphene oxide/metal organic framework based electrochemical sensor coupled with machine learning for sensitive detection of penta-chlorophenol.
We recently reported that air cell administration of penta-brominated diphenyl ether (penta-BDE; DE71) evokes biochemical and immunologic effects in chicken (Gallus gallus) embryos at very low doses, and impairs pipping (i.e., stage immediately prior to hatching) and hatching success at 1.8 lg g 1 egg (actual dose absorbed) in American kestrels (Falco sparverius). In the present study, absorpti...
The Cu(I)-catalyzed Ullmann condensation reaction between aliphatic alcohols and sym-pentachlorocorannulene provides a convenient entry to 1,3,5,7,9-pentaalkoxycorannulenes. The latter are easily converted to novel deca-heterosubstituted derivatives, such as 1,3,5,7,9-penta-X-2,4,6,8,10-penta-Y-corannulenes by electrophilic aromatic substitution.

Abstract Penta-graphene is a new two-dimensional metastable carbon allotrope composed entirely of pentagons with unique electronic and mechanical properties. In this work we evaluate the properties classes defective penta-graphene (DPG) subjected to tensile shear loading by using molecular dynamics simulations. The types defects considered here are monovacancy at either 4-coordinated C1 site or...
