Abstract:
1. A co-crystal comprising cyprodinil and a co-crystal forming compound which has at least one organic acid functional group, wherein said co-crystal forming compound is: a) benzoic acid and the co-crystal is characterised by a powder X-ray diffraction pattern expressed in terms of 2 theta angles, wherein the powder X-ray diffraction pattern comprises the 2 theta angle values 11.201, 11.660, 13.978, 15.050, 18.584,19.297, 20.793, 23.865, 25.697, and 26.765; or b) succinic acid and the co-crystal is characterised by a powder X-ray diffraction pattern expressed in terms of 2 theta angles, wherein the powder X-ray diffraction pattern comprises the 2 theta angle values 12.5, 17.3, 18.7, 21.0, 22.4, 24.0, 25.4, 28.8 and 29.3; and wherein hydrogen-bonding occurs between the co-crystal forming compound and the cyprodinil.
