It occurs as tabular to platey monoclinic green to yellow green crystals.

==Discovery and occurrence==

It was first described in 1935 for an occurrence in the Chuquicamata Mine, Antofagasta, Chile, and named for Swedish–American economic geologist Waldemar Lindgren (1860–1939) of the Massachusetts Institute of Technology.<ref name=HBM/><ref name=Mindat/>

Lindgrenite occurs in the oxidized portions of copper–molybdenum bearing sulfide ore deposits. Associated minerals include antlerite, molybdenite, powellite, brochantite, chrysocolla, iron oxides and quartz.<ref name=HBM/>
