| Abstract
| - The polymeric solids [Ph3PCH2Ph]2[Zn3(tp)3Cl2] (1) and Ni3(tma)2(H2O)8 (2) crystallize in two remarkable 2D claylike lamellar architectures constructed by linear metal trinuclear clusters and rigid linear tp or trigonal tma ligands, displaying a novel 2D 6-linked (3,6) topological network in 1 and an interesting 2D 3,6-linked molybdenite topological network in 2, respectively. The novelty for 1 is in the ionic exchange activity that its large bulky interlayer [Ph3PCH2Ph]+ guest is exchangeable.
- Two new compounds, [Ph3PCH2Ph]2[Zn3(tp)3Cl2] (1) and Ni3(tma)2(H2O)8 (2) (tp = terephthalate, tma = trimesate),are metal−polycarboxylate coordination polymers prepared by similar hydrothermal synthesis techniques. X-raysingle-crystal structural analysis shows that both compounds crystallize in the 2D claylike lamellar architectures, inwhich 1 possesses the interlayer [Ph3PCH2Ph]+ exchangeable cation and has been confirmed by PXRD patterns.1 (C74H56Cl2O12P2Zn3) belongs to monoclinic P21/c, Z = 2 (a = 18.956(1) Å, b = 10.2697(5) Å, c = 17.067(1) Å,β = 99.486(4)°). 2 (C18H22O20Ni3) is attributed to triclinic P1̄, Z = 1 (a = 6.6643(8) Å, b = 9.622(1) Å, c =10.089(1) Å, α = 112.675(2)°, β = 94.007(1)°, γ = 106.411(2)°). Linear metal trinuclear clusters bridged by rigidlinear tp ligands for 1 and trigonal tma ligands for 2 give rise to a novel 2D 6-linked (3,6) topological anionicnetwork in 1 and an interesting 2D 3,6-linked molybdenite topological neutral network in 2, respectively. Bothcompounds exhibit intense fluorescent emission bands at 410 nm (λexc = 355 nm) for 1 and 398 nm (λexc = 300nm) for 2 in the solid state at room temperature.
