The first open-framework metal phosphoxalate compound containing both an organic and an inorganic template in the same structure is reported. Na(H{sub 3}N{sup +}CH{sub 2}CH{sub 2}N{sup +}H{sub 3}){sub 0.5}[Co(C{sub 2}O{sub 4})(HPO{sub 4})] (1) was synthesized hydrothermally via a direct metathesis reaction using the sodium salts of oxalate and phosphate in the presence of cobalt chloride and ethylenediamine dihydrochloride. The structure of 1 consists of a 3D framework built from the [Co(C{sub 2}O{sub 4})] {sub n} layers connected by HPO{sub 4} {sup 2-} group bridging two different cobalt centers between the adjacent layers. A major and a minor structural tunnels are created and occupied by the Na{sup +} and H{sub 3}N{sup +}CH{sub 2}CH{sub 2}NH{sub 3} {sup 2+} ions, respectively, in the same structure. Single-crystal X-ray crystallographic data for 1 are: monoclinic, P2{sub 1}/c, a=5.8189(6), b=10.235(1), c=13.066(1) A, {beta}=96.671(2){sup o}, Z=4, V=772.9(1) A{sup 3}, R=3.95% and R {sub w}=6.37%. - Graphical abstract: View along a of the structure of Na(H{sub 3}NCH{sub 2}CH{sub 2}NH{sub 3}){sub 0.5}[Co(C{sub 2}O{sub 4})(HPO{sub 4})] exhibiting 3D tunnels created and occupied by the Na{sup +} and H{sub 3}NCH{sub 2}CH{sub 2}NH{sub 3} {sup 2+} cations.
