Code Sample, a copy-pastable example if possible

version 1

conda create --name test_chemcoord -c mcocdawc chemcoord

version 2

conda create --name test_chemcoord 
source activate test_chemcoord
conda install -c mcacdawc chemcoord

version 3

conda create --name test_chemcoord 
conda install --name test_chemcoord -c mcocdawc chemcoord

All three give the error:

Fetching package metadata .............
Solving package specifications: 

PackageNotFoundError: Packages missing in current channels:
            
  - chemcoord -> pymatgen

Problem description

The dependency for pymatgen is not resolved via conda install.
The installation and usage works flawlessly with pip install chemcoord, though:
In the root environment conda list outputs among others chemcoord 2.0.2 <pip>.

I don't know how to tell conda to use dependencies from other cannels than default.
You can install chemcoord with conda, if you manually add conda-forge or matsci as channels.
(In general it is a good idea anyway to add conda-forge).

I leave the issue open. Perhaps someone comes up with a good idea.

since chemcoord is on conda-forge now anyway, this issue is solved.
