Compounds {[Ba₃(tpmm)(H₂O)₁₅]·5H₂O}_n (1) and {[Ba₆(tpmm)₂(H₂O)₂₂]·15H₂O}_n (2) were obtained through reactants slowly diffusion of barium acetate (Ba(CH₃COO)₂) and 2,4,6-tris(phosphorylmethyl)mesitylene (H₆tpmm) at room temperature in H₂O/THF/MeOH media without and with the addition of pyrazine (pz), respectively. Single-crystal X-ray structure analysis shows that compound 1 features a two-dimensional (2D) layer structure, with an I¹O¹ connectivity, in which the one-dimensional (1D) inorganic Ba−O−Ba double-stranded ribbon-like chains are cross-linked by the cis,cis,cis-configured μ₃-tpmm⁶⁻ anions. Compound 2 has also a 2D layer structure but with an I²O⁰ connectivity, in which the 2D inorganic Ba−O−Ba layer is capped by the cis,cis,cis-configured μ₄- and μ₃-tpmm⁶⁻ anions. Of interest, in 2 there are significant cation−π interactions between the Ba²⁺ ion and the phenyl core of the μ₄-tpmm⁶⁻ anion. Compounds 1 and 2 both display a high thermal stability approaching to 402 °C and 545 °C, respectively, and emit three ligand-based emission bands in the solid-state at room temperature.
