“…Thus, the number of structures in the Cambridge Structural Database (CSD version 5.38, latest update May 2017; Groom et al, 2016) is limited to 20 (after the exclusion of duplicated structures). These comprise: one mononuclear complex (MOKCEU; Murugavel & Sathiyendiran, 2001); four binuclear complexes [DAVFEM (Shiraishi et al, 2005), ENIMUJ (Yashiro et al, 2003), YIWYUA and YIWZAH (Pothiraja et al, 2014) (Bian et al, 2004;Kuroda-Sowa et al, 2005) and XUBXOH/XUBXOH01 (Kuroda-Sowa et al, 2002]; eight coordination polymers [KOZZAC and KOZZUW (Rajakannu et al, 2015), LULGEE (Sathiyendiran & Murugavel, 2002), ODEWOK (Rafizadeh et al, 2007), SAMNEA/SAMNEA01 (Pothiraja et al, 2004(Pothiraja et al, , 2005, TEKQOR and TEKQUX (Dey et al, 2013) and WENSUE (Rafizadeh et al, 2006)]. All of the above are heteroleptic complexes containing the following di-substituted organophosphate ligands:…”
