Fig. 4From: Induced secondary metabolites of the beneficial fungus Trichoderma harzianum M10 through OSMAC approachThermal ellipsoids representation of chromone drawn at 50% probability (left side) and crystal packing arrangement of chromone (right side). Atoms are color coded as follows: carbon (gray), oxygen (red), nitrogen (blue) in balls-and-sticks representation. Crystal packing arrangement shows pi-pi interactions along the b-axisBack to article page
