Tetranuclear Nickel(II) Complexes Composed of Pairs of Dinuclear LNi2 Fragments Linked by Acetylenedicarboxylate, Terephthalate, and Isophthalate Dianions: Synthesis, Structures and Magnetic Properties

“…[ [40][41][42] www.eurjic.org In summary, all three new compounds are discrete tetranuclear nickel(II) complexes composed of pairs of bioctahe-…”

Two Novel Diamagnetic-metal Coordination Polymers of Nitronyl Nitroxide Radical Incorporating Isophthalate Bridges

“…The phenyldicarboxylates (terephthalate, isophthalate and phthalate) are versatile ligands owing to their good binding ability and the diversity of their bonding modes, as exemplified by the formation of polymeric structure systems [14][15][16][17][18][19]. Several multi-dimensional coordination polymers of metal-nitroxide radicals incorporating terephthalate bridges have been reported [20][21][22][23].…”

Synthesis, Crystal Structure, and Magnetic Properties of Two Manganese(II) Polymers Bearing Ferrocenecarboxylato Ligands

“…The Mn-O bond lengths of complex 1 are in the range 2.035(2)-2.227(3) Å (Table 1), which is comparable to those in related complexes. [3,12] The O-Mn-O angles range from 83.18 to 180.0° (Table 1). An interesting feature is the construction of the [Mn 2 (FcCO 2 ) 4 ] building block as shown in Figure 2.…”

“…[3,4] Carboxylato ligands have been widely used because they can exist in diverse coordination modes such as terminal monodentate, chelating to one metal center, and bridging bidentate, in a syn-syn, syn-anti, or anti-anti configuration to two metal centers. [5,6] However, However, the two Mn II ions in the dinuclear [Mn 2 (FcCO 2 ) 4 ] units of complex 2 are bridged only by two carboxylato ligands, and the other two ferrocenecarboxylato ligands in this unit bind in a chelating mode.…”
