“…Due to the various coordination modes that carboxylates can adopt, different structures with copper(II) have been resolved by X-ray diffraction methods [14 and references therein, 15,16], ranging from binuclear tetrakis -carboxylate complexes, which exhibit well-characterized paddle-wheel cage-like structures [17,18], to mononuclear dicarboxylate complexes [9], involving diverse stereochemistries with different numbers of bridging bidentate carboxylates [14].…”

Eight new copper(II) complexes with halo-aspirinate anions have been synthesized: [Cu 2 (Fasp) 4 (MeCN) 2 ] Á 2MeCN (1), [Cu 2 (Clasp) 4 (MeCN) 2 ] Á 2MeCN (2), [Cu 2 (Brasp) 4 (MeCN) 2 ] Á 2MeCN (3), {[Cu 2 (Fasp) 4 (Pyrz)] Á 2MeCN} n (4), {[Cu 2 (Clasp) 4 (Pyrz)] Á 2MeCN} n (5), [Cu 2 (Brasp) 4 (Pyrz)] n (6), [Cu 2 (Clasp) 4 (4,4 0 -Bipy)] n (7), and [Cu 2 (Brasp) 4 (4,4 0 -Bipy)] n (8) (Fasp: fluor-aspirinate; Clasp: chloro-aspirinate; Brasp: bromo-aspirinate; MeCN: acetonitrile;Pyrz: pyrazine; 4,4 0 -Bipy: 4,4 0 -bipyridine). The crystal structure of two 2 and 4 have been determined by X-ray diffraction methods. All compounds have been studied employing elemental analysis, IR, and UV-Visible spectroscopic techniques. The results have been compared with previous data reported for complexes with similar structures.
