“…To date, carboxylate-based ligands (RCO 2 – ) are some of the most prevalent ligands due to their well-known reaction and coordination behavior. Many carboxylate ligands are easily accessible, relatively stable and offer a variety of possible coordination modes, such as monodentate, chelating, and bridging . This renders them versatile ligands for the synthesis of molecular complexes [e.g., M 2 (OAc) 4 , where M = Cu(II), Rh(II), Cr(II), or Mo(II)] as well as extended coordination polymers (CPs) {e.g., [ZnO 4 (BDC) 3 ] (BDC 2– = benzene-1,4-dicarboxylate) or [Cu 3 (BTC) 2 ] (BTC 3– = benzene-1,3,5-tricarboxylate)}. , While acetate and oxalate ligands are typically used to create discrete coordination complexes, aromatic bis- and tris-carboxylates, such as terephthalate (BDC 2– ) and trimesate (BTC 3– ), are commonly used for the construction of extended metal–organic CPs .…”

Benzene-1,3,5-tri(dithiocarboxylate) (BTDTC3–), the sulfur-donor analogue of trimesate (BTC3–, benzene-1,3,5-tricarboxylate), is introduced, and its potential as a multidentate, electronically bridging ligand in coordination chemistry is evaluated. For this, the sodium salt Na3BTDTC has been synthesized, characterized, and compared with the sodium salt of the related ditopic benzene-1,4-di(dithiocarboxylate) (Na2BDDTC). Single-crystal X-ray diffraction of the respective tetrahydrofuran (THF) solvates reveals that such multitopic aromatic dithiocarboxylate linkers can form both discrete metal complexes (Na3BTDTC·9THF) and (two-dimensional) coordination polymers (Na2BDDTC·4THF). Additionally, the versatile coordination behavior of the novel BTDTC3– ligand is demonstrated by successful synthesis and characterization of trinuclear Cu(I) and hexanuclear Mo(II)2 paddlewheel complexes. The electronic structure and molecular orbitals of both dithiocarboxylate ligands as well as their carboxylate counterparts are investigated by density functional theory computational methods. Electrochemical investigations suggest that BTDTC3– enables electronic communication between the coordinated metal ions, rendering it a promising tritopic linker for functional coordination polymers.
