I would think that bond should be the same distance (within hundredths
of an Ångstrom) as the other 5 carbon-carbon bonds in the benzene
ring. That whole molecule is aromatic, by the way.
I can't answer the "how come" question except to say that is most
likely wrong, due to making wrong as
Thanks Bill for clarifying the notion of aromatic bonds
I think the C-C bond shared by the benzene and imidazole ring should
be close to a double bond distance

How come calculation from monomer sketcher and the BZI entry in the
library has a distance cl

Is there a clear definition of delocalized bond or armatic bond?
Hi Zheng:
Aromatic bonds only occur in planar cyclic molecules that have 4n +2
pi electrons. Aromatic interactions give energetic stabilization

Dear all
I ran into a problem with monomer sketcher. One of my compounds has a
benzimidazole group.
C12=CC=CC=C1N=CN2
When I used monomer sketcher regularizing with refmac, the C-C bond
that connect the benzene ring and the imidazole has a length of 1.49
A. I defined them as delocalized bond.
