Unusual coordination of tetrylenes to molybdenum carbonyl fragments.
Reactions of the tetrylenes Ge(SAr(Me6))2 (1) (Ar(Me6) = C6H3-2,6(C6H2-2,4,6-Me3)2), and Sn(SAr(Me6))2 (2) with (Mo(CO)4(NBD) (NBD = bicyclo[2.2.1]hepta-2,5-diene) gave three new, unusual complexes [Mo(THF)(CO)3{Ge(SAr(Me6))2}] (3), [Mo(THF)(CO)3{Ge(SAr(Me6))2}] (4) and [Mo(CO)4{Sn(SAr(Me6))2}] (5) which display no significant Ge/Sn-Mo bonding. Instead the ligands are coordinated to molybdenum ...
متن کاملA Rare Case of Maxillary Compound Odontoma with an Unusual Large Number of Denticles
Odontoma is the most frequent odontogenic gnathic tumor, which is considered to be a hamartomatous lesion rather than an actual odontogenic tumor. Odontoma is basically composed of enamel and dentin, while it could also have various contents of cementum and pulp tissue. These lesions may manifest in two specific forms, including the compound type with multiple, small, tooth-like structures and ...
متن کاملThe coordination number of granular cylinders
– We report the first experimental measurements of the contact number distribution between randomly packed granular right cylinders (rods and disks) as a function of aspect ratio. The average coordination number 〈z〉 for cylinders varies smoothly with aspect ratio rising from 〈z〉 ∼ 6 for aspect ratios close to one to 〈z〉 ∼ 10 for large aspect ratio. Additionally, our measurements demonstrate the...
متن کاملExtraction of Molybdenum (VI) and Vanadium (V) from Nitrate Solutions Using Coupling of Acid and Solvating Extractants (RESEARCH NOTE)
In this study, solvent extraction method has been utilized for separation of molybdenum and vanadium from nitrate solution by utilizing coupling of acid and solvating extractants (D2EHPA and TBP extractants). The outcomes demonstrated that synergistic solvent extraction improves stability of formatted complexes for transfer to the organic phase. The main parameters such as pH value, concentrati...
متن کاملUnusual State in V Sagittae
It has been recently demonstrated that the recurring high/low states in the peculiar binary V Sge can be explained by considering the limit-cycle oscillation involving negative feedback by the wind on the mass-transfer from the secondary star. We noticed, from the recent observations reported to the VSNET, the presence of a different state of recurring variations (recurrence time ∼ 30 d) showin...
