What molecule is shown in the Halifax boardwalk sculpture?

[DaveC426913]

This molecule has been immortalized in a sculpture on the boardwalk of the city of Halifax, NS.

Wondering if anyone recognizes it.

I see it has a carbon backbone and a benzene ring, but I don't know much else. I'm afraid that, other than the arrangements and bonds, there's no indication do what the various individual atoms are. And it has no name, so no help there.

I tried to guess what molecule might be significant to Haligonians, but it is clearlry not a molecule of TNT or nitroglycerin!

Ideas?

The city of Halifax had an explosion in 1917, a very large explosion. That maybe has some significance with the statue,other than that i think it could be a plastic or an organic ester of some sort.http://en.wikipedia.org/wiki/Halifax_Explosion

It is nearly Nitrocellulose (gun cotton) http://en.wikipedia.org/wiki/Nitrocellulose
Could be a bit of artistic licence, or the sculptor wasn't up on his chemistry?

Without knowing which of the 'balls' are carbon, hydrogen, nitrogen, sulfur, oxygen... it is not possible to know. For example, the 'benzene' ring has substitution at the 12 o'clock and 6 o'clock position that could be protons. There is no substitution at the 10 o'clock position which indicates that the 10 o'clock position is occupied by something other than carbon (perhaps nitrogen). The branched chain on the left shows protons on the methyl groups (I think) so it appears that the sculptor intends to show protons if they are present. The benzo-fused 5-member ring on the right side of the benzene (?) ring shows at least two positions (exo to the 6-member ring) that contain a hetero atom (N, S, O) but without knowledge of the electronic nature of the bonds in that ring (single, double, aromatic) it is impossible to tell.

Perhaps it is just art intended to reflect the city's association with Science and Technology (Dalhousie University?).

Indeed.

It knocked objects off shelves in Truro, 100km away and was heard 360km away in Cape Breton.

It is heralded as the largest manmade explosion in history, up until the bomb at Hiroshima. And at 3 kilotons, it rivals even that, which was a mere 13kT.
