Low-Spin Pseudotetrahedral Iron(I) Sites in Fe2(μ-S) Complexes

by John S. Anderson, Jonas C. Peters

Abstract

FeI centers in iron–sulfide complexes have little precedent in synthetic chemistry despite a growing interest in the possible role of unusually low valent iron in metalloenzymes that feature iron–sulfur clusters. A series of three diiron [(L3Fe)2(μ-S)] complexes that were isolated and characterized in the low-valent oxidation states FeII[BOND]S[BOND]FeII, FeII[BOND]S[BOND]FeI, and FeI[BOND]S[BOND]FeI is described. This family of iron sulfides constitutes a unique redox series comprising three nearly isostructural but electronically distinct Fe2(μ-S) species. Combined structural, magnetic, and spectroscopic studies provided strong evidence that the pseudotetrahedral iron centers undergo a transition to low-spin S=1/2 states upon reduction from FeII to FeI. The possibility of accessing low-spin, pseudotetrahedral FeI sites compatible with S2− as a ligand was previously unknown.

A new spin on FeI:FeI centers: A unique series of diiron [(L3Fe)2(μ-S)] complexes were isolated and characterized in the low-valent oxidation states FeII[BOND]S[BOND]FeII, FeII[BOND]S[BOND]FeI, and FeI[BOND]S[BOND]FeI as nearly isostructural but electronically distinct species. Structural, magnetic, and spectroscopic studies indicated a transition of the pseudotetrahedral iron centers to low-spin S=1/2 states upon reduction from FeII to FeI (see scheme).

Pyro Board: An Audio Visualizer Created from an Array of 2,500 Flames

by Christopher Jobson

Pyro Board: An Audio Visualizer Created from an Array of 2,500 Flames sound science fire

So here’s a thing to never try at home. Derek Muller from the very fine science video blog Veritasium visits with a team of “phsyics and chemistry demonstrators” who built this ridiculous sound board that demonstrates the effect of sound waves traveling through flammable gas. The first half deals mostly with how it works, around 3:38 it turns into pure music and fire.

Free Speech

I can't remember where I heard this, but someone once said that defending a position by citing free speech is sort of the ultimate concession; you're saying that the most compelling thing you can say for your position is that it's not literally illegal to express.

This Machine Folds Paper Planes, Then Flies Them Into The Recycling Bin

Humans have been rendered obsolete, at least where the paper airplane is concerned. This machine will fold a plane and launch it, sending it straight into the recycling bin.

Orbital Mechanics

To be fair, my job at NASA was working on robots and didn't actually involve any orbital mechanics. The small positive slope over that period is because it turns out that if you hang around at NASA, you get in a lot of conversations about space.

Пусси Райот - предатели

by tema@tema.ru
Группа Пусси Райот, пострадав от святой инквизиции, окончательно сошла с ума.

Раньше был настоящий крутой панк. "Богородица, Путина прогони!" на Лобном месте - прекрасный коктейль для троллинга.




А сейчас что? Девки ездят по заграничным телевизионным шоу, встречаются с известными артистами и политиками. Это как, блять? Со старушкой Крупской лучок заебашить?




"Пусси Райот" переводится с английского как "Пиздобунт".

Почему они как октябрята на концерте Мадонны скромно стоят на сцене? Почему не сдернут с себя майки, чтобы на сиськах было написано "Мадонна - тупая пизда"?

Почему не засунули Маккартни в жопу микрофон?

Почему в вечернем шоу на ТВ у Кольберта не выкрикивали истерично "Обама - пидарас"? Вместо этого сидели и тупо отвечали на вопросы.

Это же была панк-группа. А превратилась в какое-то сраное толерантное говно.

Предали панк.

Kermit the Frog & Fozzie Bear Hilariously Engage In Improvised Existential Banter During 1979 Camera Test

by Lori Dorn

Kermit the Frog (Jim Henson) and Fozzie Bear (Frank Oz) hilariously engage in improvised existential banter about their greater state of being during this 1979 camera test for their first “live-action” film, The Muppet Movie.

Kermit: Well Fozzie, the thing of it is though you’re not a real bear. You’re not a real natural bear. I mean, you’re talking about a bear in its natural habitat…What do you have, you have sort of a fake fur. You’ve got foam rubber. You’ve got foam rubber and fake fur. You’re an artificial bear. Have you ever seen a bear with a magenta nose?

Fozzie: I got news for you kid. You have to hurt me, I’m going to have to hurt you. Are you ready for this? Are you ready? You got a wire on your arm. It’s only for movement. I’m sorry, I didn’t mean to hurt you. I believe in you. I do understand that I am not a real bear but I know what I am. I am what I am. But I’m a real puppet. I’m happy with my lot in life.

Absolutely priceless.
