N2 - A novel layered framework of tin(II) phosphate, [Sn4(PO 4)3-(OH)]2-·[trans-1,2-C 6H10(NH3)2]2+, has been synthesized under hydrothermal conditions with tin(II) oxalate, phosphoric acid and a mixture of trans- and cis-1,2-diaminocyclohexane (1,2-DACH). The compound crystallizes in the monoclinic space group P21/n (No. 14). The channels of the trans-1,2-DACH are occluded by hydrogen bonding in the doubly protonated form, which is leached out from the framework. Reaction using only tran-DACH gives the same compound. For comparison, when cis-DACH is used as template under the same conditions instead of the mixture of trans and cis isomers, the neutral inorganic phosphate framework (Sn3O) 2-(Sn2O)2(PO4)4 is formed. It crystallizes in the triclinic space group P1 (No. 2). These results suggest that trans-1,2-DACH is selectively occluded in the framework [Sn 4(PO4)3(OH)]2-· [trans-1,2-C6H10(NH3)2] 2+.
