“…The crystal structures of acesulfame and its metal complexes have been reported previously (Beck et al, 1985;Bulut et al, 2005;Cavicchioli et al, 2010;İçbudak et al, 2005a;İçbudak et al, 2006;İçbudak et al, 2007b;Şahin et al, 2009;Şahin et al, 2010;Velaga et al, 2010). Furthermore, NMR (Beck et al, 1985), electronic (İçbudak et al, 2006; İçbudak et al, 2007a; İçbudak et al, 2007b), IR (Beck et al, 1985;İçbudak et al, 2006;İçbudak et al, 2007a;İçbudak et al, 2007b), mass (İçbudak et al 2005b) spectroscopies, thermal analysis (İçbudak et al, 2005b; İçbudak et al, 2006; İçbudak et al, 2007a; İçbudak et al, 2007b), magnetic susceptibility (İçbudak et al, 2006; İçbudak et al, 2007a), conductivity (İçbudak et al, 2007b) studies have been performed on the metal complexes of acesulme. In addition, the stability belong to different form of the acesulfame have being studied (Velaga et al, 2010).…”

“…For background to acesulfame [systematic name: 6-methyl-1,2,3-oxathiazin-4(3H)-one 2,2-dioxide], see: Clauss & Jensen (1973); Duffy & Anderson (1998);O'Brien Nabors (2001); İçbudak et al (2006) For the crystal structures of acesulfame and its metal complexes, see: Beck et al (1985); Bulut et al (2005); Cavicchioli et al (2010); İçbudak et al (2005a, 2006, 2007b); Ş ahin et al (2009,2010); Velaga et al (2010) and for spectroscopic, thermal analysis, magnetic susceptibility and conductivity studies on metal complexes of acesulfame, see: Beck et al (1985); İçbudak et al (2005a,b, 2006, 2007a,b). For Cu 2+ complexes with an octahedral coordination geometry, see: Bulut et al (2005); İçbudak et al (2007b); Pariya et al (1998a,b); Ş ahin et al (2010).…”

“…The Pd-N distance is 2.127 (2) Å, significantly longer than the Pt-N distance (2.036 (3) Å) in another square-planar d 8 complex, K 2 [trans-Pt(Ace) 2 Cl 2 ] (Cavicchioli et al, 2010;Beck et al, 1985), but much shorter than those in divalent latemetal N-acesulfamates with octahedral Jahn-Teller distortion: 2.7175 (16) Å in trans-Cu(c-C 6 H 10 -1,2-(NH 2 ) 2 )(Ace) 2 (Şahin et al, 2010) and 2.3180 (19) Å in trans-Co(H 2 O) 4 (Ace) 2 (İçbudak, 2005 in fluorobenzene at 24 °C. The complex was characterized by NMR in CDCl 3 .…”

“…For the low toxicity of acesulfamate, see: Lipinski (2003). For examples of different modes of acesulfamate bonding to transition metals, see: Bulut et al (2005); Cavicchioli et al (2010); Ş ahin et al (2009,2010); Dege et al (2006Dege et al ( , 2007; Beck et al (1985); İçbudak et al (2005).
