When I tested this earlier, I was indeed using dejavu... In the chemistry macros, we are using a particular version of mathematics mode (subscripts, superscripts, ...) but in normal font, so greek characters, etc. will work if the font includes them.

Re: [NTG-context] Drawing chemical structures
Indeed, there have been a few changes, several rationalizations of the syntax: 1. FIVE,FRONT has become FIVEFRONT 2. positions are numbered coherently with FIVE (previously they were shifted by one) 3. +R and -R have become LR and RR, to be coherent with the non-front structures. 4. Thus, +LSR and -RSR are the asymmetrically shortened versions drawing bonds. 5. One can still use dimensional measurements in the thousands, but it is preferable to use numbers close to unity, interpreted in units of the bond length. 6. The bounding box is by default fit (in ppchtex it was fixed 4000x4000). Placing labels thus generally requires specifying a top or bottom dimension. Below is your example, corrected. (For some reason, unicode \alpha currently disappears - a font issue. This worked early so is indeed a bug.) A complete new manual has been written. We are currently hung on one or two minor details that Hans and myself have not yet take care of - just a question of getting around to it. Indeed, we NEED to release the new manual...

Re: [NTG-context] Drawing chemical structures
Hello, We have completely rewritten the chemical macros from ppchtex, taking some liberty with some details of the syntax. I will look into your examples to see what is going wrong.
