• : antiferromagnetic interaction; arylthio-substituted tetrathiafulvalenes; charge-transfer; crystal structure; magnetic property; Introduction Since firstly synthesized in 1970s [1], tetrathiafulvalene (TTF) and its derivatives have been intensively studied to explore functional organic materials [2]. Inspired by

• S5 in Supporting Information File 1), which would result in the significant effect on the magnetic property as discussed in the following section. 4·CuBr4 crystallizes in the orthorhombic Pccn space group with half of molecule 4 and half of CuBr4 crystallographically independent (Figure 3a). The
