A composition space diagram is used to establish the stability regions of hybrid fluoroaluminates synthesized by solvothermal reactions in the Al(OH) 3-HguaCl-HFaq-EtOH system. The syntheses are conducted using microwave heating at 190 °C for 1 h. The structures of two new guanidinium fluoroaluminates, (H3O)2-[HgUa] 16(Al4F18)3.H2O and [Hgua]2-(Al5F17), are reported. (H 3O)2-[Hgua]16-(Al4F 18)3-H2O, determined from single-crystal X-ray data, consists of discrete (Al4F18)6- polyanions, while [Hgua]2-(Al5F17), solved from powder X-ray diffraction data in direct space, contains unprecedented Al 5F17 layers constructed from the intergrowth of HTB and perovskite columns. A disorder of H2O and H3O+ is evidenced in (H3O)2-[Hgua]16-(Al 4F18)3-H2O together with a disorder of guanidinium cations in the interlayer space of [Hgua]2-(Al 5F17). (
