I just came across your message from over a month ago...
Here is my solution (ConTeXt):
\usemodule[chemic]
\starttext
% 18-Crown-6
\startchemical[width=fit,height=fit]
\chemical[SIX,B5,-SB4,+SB6,Z4,MOV1][O]
\chemical[SIX,B6,-SB5,+SB1,Z5,MOV2][O]
\chemical[SIX,B1,-SB6,+SB2,Z6,MOV3][O]
\chemical[SIX,B2,-SB1,+SB3,Z1,MOV4][O]
\chemical[SIX,B3,-SB2,+SB4,Z2,MOV5][O]
\chemical[SIX,B4,-SB3,+SB5,Z3][O]
\stopchemical
% my discotic mesogene...
\startchemical[width=6500,height=8000,top=2500,left=2500]
\chemical[SIX,B5,-SB4,+SB6,PB:Z4,ONE,SB6,Z06,PE,MOV1][N,R]
\chemical[SIX,B6,-SB5,+SB1,PB:Z5,ONE,SB7,Z07,PE,MOV2][N,R]
\chemical[SIX,B1,-SB6,+SB2,PB:Z6,ONE,SB8,Z08,PE,MOV3][N,R]
\chemical[SIX,B2,-SB1,+SB3,PB:Z1,ONE,SB2,Z02,PE,MOV4][N,R]
\chemical[SIX,B3,-SB2,+SB4,PB:Z2,ONE,SB3,Z03,PE,MOV5][N,R]
\chemical[SIX,B4,-SB3,+SB5,PB:Z3,ONE,SB4,Z04,PE][N,R]
\stopchemical
\stoptext
