Hi Johannes,

I looked at your coding.
The use module line has two typo's It should be \usemodule[pictex,chemic]
The statements are not complete i.e. you forgot  the \stopcombination. 
Further when starting a combination one needs to give the number of rows 
and columns e.g. [2*3]. with only [6] all of the structures are placed 
inline, but only 4 of them fit in one row  so ...
In order to produce output you need to enclose the code between 
\starttext ... \stoptext.

Please see the attached file

Kind regards

Willi
