N2 - Two new layered gallophosphates Co(en)3·Ga 3P4O16·5H2O (1) and trans-Co(dien)2·Ga3P4O 16·3H2O (2) have been hydrothermally synthesized using the racemic mixture of chiral metal complex Co(en)3Cl 3 and Co(dien)2Cl3 as the structure-directing agent, respectively. Their structures are determined by single-crystal X-ray diffraction analysis and further characterized by X-ray power diffraction, ICP, elemental, and TG analyses. The structures of 1 and 2 consist of vertex-linking GaO4 and PO3(=O) tetrahedral units forming macroanionic [Ga3P4O16]3- sheets with a 4.6-net. The 4.6-net is characteristic of chiral [3.3.3] propellane-like structural motifs. The sheets of 1 stack in an ABAB sequence, with a pair of enantiomers of chiral Co(en)33+ cations residing in the interlayer region. The sheets of 2 array in a helical fashion with an ABCDEF stacking sequence, with only one enantiomer of chiral Co(dien)23+ cations residing in the interlayer region. Structural elucidation of 1 and 2 reveals that there exist stereo-specific correspondence between the metal complex template and the structure of the inorganic host. Crystal data: 1, Co(en)3·Ga3P4O16· 5H2O, orthorhombic, Pnna (No. 52), a=8.6618(2)Å, b=21.6071(5)Å, c=13.7426(4)Å, Z=4, R1=0.0337 (I>2σ(I)), wR2=0.0985 (all data); 2, Co(dien) 2·Ga3P4O16·3H 2O, hexagonal, P6522 (No. 179), a=8.5152(7)Å, b=8.5152(7)Å, c=63.278(8)Å, R1=0.1183 (I>2σ(I)), wR2=0.2864 (all data) and Z=6.
