N2 - A novel open-framework silicogermanate SU-JU-14 (Stockholm University-Jilin University-Number 14), |NH 3CH 2CH 2NH 3| 3[Ge 6.40Si 0.60O 15(OH)] 2[Ge 0.73Si 3.27O 8], was synthesized by using ethylenediamine as the structure-directing agent under solvothermal conditions. Single-crystal structure analysis reveals that the crystal structure of SU-JU-14 consists of extended 24-ring channels built from [(Ge,Si) 7O 12O 6/2(OH)] 3- [(Ge,Si) 7] clusters and unbranched zweier silica double chains [Ge 0.73Si 3.27O 4O 8/2]. Charge neutrality is achieved by diprotonated ethylenediamine guest molecules. The structure consists of stacking faults of layered arrays in two different configurations along the a-axis. SU-JU-14 was characterized by X-ray diffraction, X-ray energy dispersive spectroscopy, scanning electron microscopy, nuclear magnetic resonance, inductively coupled plasma, and thermogravimetric analyses. Crystallographic data: monoclinic, space group C2/c, and unit cell parameters: a = 35.625 (7) Å, b = 28.580 (6) Å, c = 10.403 (2) Å, and β = 98.30 (3)°.
