Network analysis of barium oxalates Ba(C2O4)m(HC2O4)n(H2C2O4)p(H2O)q, including the new, uniform, five-connected loh net

• The structures of three compounds from the system Ba(C2O4)m(HC2O4)n(H2C2O4)p(H2O)q have been structurally reinvestigated by low-temperature X-ray diffraction. Ba(C2O4)(H2O)2, 1, Ba(C2O4)(H2C2O4)(H2O)2, 2, and Ba(C2O4)0.5(HC2O4)(H2O), 3. The compounds are composed of three-dimensional coordination network structures with bridging oxalates and water molecules. Compound 1 is binodal, four and five connected with topology (4462)(4466)-tcs; 2 contains the common 66-dia net and 3 displays the new uniform network topology 610-loh. Together with the recently reported 610-ghw and 610-rld-z nets, and the 610-fnu net, the loh net forms a subclass of five-connected 610-nets based on the distorted trigonal bipyramidal coordination.
