By using amines with different lengths, two layered cobalt-molybdenum phosphates with different interlayer distances, (C{sub 2}N{sub 2}H{sub 10}) [HCo(H{sub 2}O){sub 2}P{sub 2}MoO{sub 10}] (1), and (C{sub 3}N{sub 2}H{sub 12}){sub 4{l_brace}}Co{sub 3} [P{sub 4}Mo{sub 6}O{sub 26}(OH){sub 5}]{sub 2{r_brace}}. 5H{sub 2}O (2), have been hydrothermally synthesized and characterized. In compound 1, the H{sub 2}en direct the [CoMoP{sub 2}] clusters to form a layered framework. By changing the lengths of protonated organic amines (H{sub 2}en to 1, 3-H{sub 2}pn), compound 2 is obtained, in which the sandwich-shaped [Co (Mo{sub 6}P{sub 4}){sub 2}] clusters are linked by tetrahedrally coordinated cobalt into a layered framework. With the lengths of protonated organic amines increasing, the interlayer distances in compound 2 become larger. This work successfully demonstrates that tuning the lengths and conformation of the protonated organic amines can provide a facile route for the formation of organically templated inorganic open-framework materials. Additionally, susceptibility measurement shows that the two compounds both exhibit antiferromagnetic interactions. -- Graphical abstract: By using amines with different lengths, two layered cobalt-molybdenum phosphates with different interlayer distances have been hydrothermally synthesized. Display Omitted Research highlights: {yields} Two layered compounds have been synthesized by utilizing amines with different lengths. {yields} The chain lengths of amines can influence the overall supramolecular framework of the PMo-TMCs. {yields} The conformation of amines may influence the stacking mode of the inorganic building blocks. {yields} Susceptibility measurement shows that the two compounds both exhibit antiferromagnetic interactions.
