Prismane
Prismane is a polycyclic hydrocarbon with the formula C6H6. It is an isomer of benzene, specifically a valence isomer. Prismane is far less stable than benzene. The carbon (and hydrogen) atoms of the prismane molecule are arranged in the shape of a six-atom triangular prism—this compound is the parent and simplest member of the prismanes class of molecules. Albert Ladenburg proposed this structure for the compound now known as benzene. The compound was not synthesized until 1973.
History
In the mid 19th century, investigators proposed several possible structures for benzene which were consistent with its empirical formula, C6H6, which had been determined by combustion analysis. The first, which was proposed by Kekulé in 1867, later proved to be closest to the true structure of benzene. This structure inspired several others to propose structures that were consistent with benzene's empirical formula; for example, Ladenburg proposed prismane, Dewar proposed Dewar benzene, and Koerner and Claus proposed Claus' benzene. Some of these structures would be synthesized in the following years. Prismane, like the other proposed structures for benzene, is still often cited in the literature, because it is part of the historical struggle toward understanding the mesomeric structures and resonance of benzene. Some computational chemists still research the differences between the possible isomers of C6H6.

Persimmon

Theology and hives spread
In New Jersey
Philadelphia and Woodstock
The Murder Mothers Move
Through the hedgefires over mud
Rings of plastic madness scorn
Ancient Rome and Egypt and Greece
The horns fall over me
Dreaming of times
And lotuses in fields of rubble
Bearded swift shift to Sophia
Opened her heart to me
Stood in her empty face touching her lips
With her fists
Biting and drawing down sparrows
By her sighing and the space of her bow
The lorries are full of gold and fog
I have the [wörterbuch] in my hand
I have misheard Adonai and brought down
Aiwass in the Mass
Corrupted Hosts by breathing grimoires
And breaking into the [Keeper's Pantry]
When I was in the desert I was
By the dedred sea see the caravan
Dragging the Sun unto set
Heard stolen cock-crow
Thieved pricks hardened by time
Into your face and her grimace
As Rainbow Patty is Goat Lady Supreme
Your throat as breathe gold spores
The little pinky
The ticker and the counter
The forged face: I have forgotten you
With Isis and persimmon you're all
All so told and spelled out
X under your name Mrs. Charlie
Poor Doll Poor Grace uninyou
Formed I heard had news from
Acidic Heaven
Home of the formerly dead
Heard have bit more than I knew was true
Ate Stars in dreams
Heard priests rant on pure
Shovelled cat shit into sinks
Gagging as the rusted sword unrolls
Tip to Teeth in κοινὴ Greece
Lord God
Let it
Day That
In Israel
Broken glass from another time
Of flogging and the ded hiding
In the bottom of the water by the headless walk
Read pornography in cherry blossom
