ISXB-4 Stellenbosch, South Africa, 23-27 March 2020

Dear Friends and Colleagues,

I take great pleasure in inviting you to attend the 4th International Symposium on Halogen Bonding (ISXB-4), which will be held in Stellenbosch, 23-27 March 2020.

ISXB-4 is the latest in the series of conferences that was initiated in 2014 by Giuseppe Resnati and Pierangelo Metrangolo. With many excellent speakers already confirmed, the first ISXB meeting on African soil promises to maintain the high standard of the previous meetings in the series, this time in the beautiful setting of the Cape Winelands region.

The conference is family-friendly, so accompanying people of all ages are most welcome. Please see the flyer and the website ( for more details.

I look forward to welcoming you to Stellenbosch in March 2020!

Best wishes,
Prof Catharine Esterhuysen
