A novel germanate [Ge 9 O 14 (OH) 12 ](C 6 N 2 H 16 ) 2 ·H 2 O ( 1 ; UTM‐4) has been synthesized under hydrothermal conditions and its structure characterized by X‐ray crystallography [ a = 9.293(2), b = 12.164(2), c = 14.564(3) Å, β = 94.96(3)°, V = 1640.1(6) Å 3 , Z = 2, monoclinic, space group P 2 1 / c ]. The structure consists of Ge−O layers of helical chains, which are linked by hydrogen bonds to form a soft, open framework that exhibits a selectivity for cis ‐1,4‐diaminocyclohexane during the synthesis.
