This macro is also very similar to \sixring
, but it
allows all 17 chemically possible combinations of double bonds,
including the three quinoid structures that can not be typeset
with \sixring
or \sixringa
.

- Arguments 1–6:
- These arguments have the
same meaning as in
\
sixring+.
- Argument 7:
- An argument of ``Q'' causes
no action. All other argument values cause an outside
double bond to be drawn from ring position 6 and the
argument itself to be put at the end of the double bond
as substituent formula R7.
- Argument 8:
- An argument of ``Q'' causes
no action. All other argument values cause an outside
double bond to be drawn from ring position 3 and the
argument itself to be put at the end of the double bond
as substituent formula R8.
- Argument 9:
- An integer number. The number
zero causes the circle to be drawn inside the ring.
All other integers are interpreted as a combination of
ring double bonds according to the bit pattern corresponding
to the decimal integer: A bit pattern of 000001 is interpreted
as a double bond beginning at ring position 1, a bit pattern
of 100000 (integer 32) as a double bond beginning at ring
position 6. Thus, argument 9 for the diagram shown above
is 9 (001001).
No action occurs for argument values that correspond to
a combination of double bonds which is chemically not
possible, namely any combination with two adjoining
double bonds.
