Hydrothermal reactions of Zn{sup II}, Ba{sup II} or Co{sup II} ion with 2-hydroxyphosphonoacetic acid (H{sub 3}L) afforded six metal phosphonates, namely, [Zn{sub 5}(O{sub 3}PCH(OH)CO{sub 2}){sub 4}(C{sub 6}H{sub 9}N{sub 2}){sub 2}] (1), [(C{sub 4}H{sub 12}N{sub 2})Zn{sub 5}(O{sub 3}PCH(OH)CO{sub 2}){sub 4}(H{sub 2}O){sub 2}] (2), [(C{sub 3}H{sub 12}N{sub 2}){sub 0.5}Zn{sub 5}(HO{sub 3}PCH(OH)CO{sub 2})(O{sub 3}PCH(OH)CO{sub 2}){sub 3}(H{sub 2}O){sub 2}].0.75H{sub 2}O (3), [BaZn{sub 2}(O{sub 3}P CH(OH)CO{sub 2}){sub 2}] (4), [Ba(HO{sub 3}PCH(OH)CO{sub 2})] (5) and [(NH{sub 4}){sub 2}Co{sub 7}(HO{sub 3}PCH(OH) CO{sub 2}){sub 6}(HPO{sub 4}){sub 2}(H{sub 2}O){sub 6}].4H{sub 2}O (6). In 1, zinc tetrahedra ([ZnO{sub 4}]) and octahedra ([ZnO{sub 5}N], [ZnO{sub 6}]) are bridged by 2-hydroxyphosphonoacetate with penta- and hexadendate modes into a hybrid layer, which is further pillared by the 3-picolylamines to form a 3D structure through Zn-N bonds and hydrogen bondings. Both 2 and 3 are 3D framework encapsulating piperazine and 1,2-propanediamine cations, respectively. In solids 4-6, the cross-linkages of [ZnO{sub 4}], [BaO{sub 10}] and [CoO{sub 6}] polyhedral with 2-hydroxyphosphonoacetate form 3D frameworks. Solids 3 and 4 behave thermally stable up to 250 and 300 {sup o}C under air atmosphere, respectively. It is interesting that the peak emission of solid 3 displays a 10 nm red-shift after simple heat-treatment. -- Graphical abstract: Six new metal phosphonates exhibit layered or 3D frameworks based on 2-hydroxyphosphonoacetate with five new coordination modes. Display Omitted Research highlights: {yields} Metal phosphonates are layered or 3D frameworks. {yields} Metal phosphonates are stable up to 250-300 {sup o}C under air atmosphere. {yields} 2-Hydroxyphosphonoacetate displays five new coordination modes.
