Sulfur as halogenbondingacceptor has been inadequately characterized. A series of thiourea motifs containing tritopic receptors with halogen-bonding acceptor capabilities were synthesized in this study via tris(isothiocyanate) intermediates. Five new halogen-bonded complexes of these receptors were described, which were accepting highly linear C−I⋅⋅⋅S interactions from three different diiodotetrafluorobenzene
