Five pseudopolymorphs of 6-amino-2-thiouracil: absence of N—H...S hydrogen bonds

“…This search yielded a total number of 39 hits, of which 29 structures contain R 2 2 (8) motifs. Nine of these structures show R 2 2 (8) motifs with two N-HÁ Á ÁO hydrogen bonds [refcodes FAJWES (Brewer et al, 1987), FICBEY , HEPMIY (Pastor et al, 1994), MUYTIK (Ivanova & Spiteller, 2010), HAFLAC (Antoniadis et al, 2003), LACJIJ (Tashkhodzhaev et al, 2002), EBAQOP (Balas et al, 2011), and EBAQOP01 and DAYGUH (Kubicki et al, 2012)] and 11 structures contain R 2 2 (8) motifs characterized by two N-HÁ Á ÁS hydrogen bonds [FALWOF (Orzeszko et al, 2004), FUWBOP (Medda et al, 2009), LOFDAL (Fonar et al, 1999), MUGMIK (Matković-Č alogović et al, 2002), PABNAJ, PABNIR (Chierotti et al, 2010), QAYCID (Van Hecke et al, 2005), QEHSEB (Tiekink, 2001), ZZZGEO01 (Delage, H'Naifi, Goursolle & Carpy, 1986), and CALFUS and CALGAZ (Tutughamiarso & Egert, 2011)]. In nine structures, two different R 2 2 (8) motifs with either two N-HÁ Á ÁO or two N-HÁ Á ÁS hydrogen bonds can be observed [CASPUI (Hu et al, 2005), GEMCAC (Read et al, 1988), PABPAL (Chierotti et al, 2010), RAPNAY (Long et al, 2005), TURCIL01 (Tiekink, 1989), TURCIL02 (Munshi & Guru Row, 2006), UXIXUV (Ferreira et al, 2011), UXIXUV01 (Tutughamiarso & Egert, 2011) and LANZIL (Al-Deeb et al, 2012)].…”
