Germanium
I 4700
11- 031
A Germanium Zeotype with a Three-Dimensional Net of Interconnected 14-, 12and 12-Ring Channels. Ge13O26(OH)4[C6N2H16]2(H2O)1.5. — Title compound (II)
crystallizes in the triclinic space group P1 with Z = 2 (single crystal XRD). Nine of the
Ge atoms are in tetrahedral coordination and the remaining four are in octahedral coordination. These polyhedra form a new type of secondary building unit building up an
open three-dimensional framework with intersecting channels. The 14-ring channels
are lined with OH- anions because all hydroxyl groups of the GeO2(OH)2 tetrahedra
point toward the 14-ring interchannel space. — (MEDINA, M. E.;
