We report the detection and analysis of several molecules arising from the WR nebula NGC 2359 around the WN4 star WR 7 (HD 56925). We have detected 3mm and 1mm rotational lines from 13CO, C18O, HCO+, CS, CN and HCN, and determined lower limits for the SiO. The survey was performed in the southeastern part of the optical nebula, where we previously inferred the presence of dense (104 cm–3) material.
