| Abstract: | Along a systematic study of open-framework materials aiming at producing new molecular sieves, we characterized a new zincophosphate Zn(HPO4)Cl[C4H10N]. It was synthesized under mild conditions (r.t.) in the presence of pyrrolidinium as an organic-structure directing agent. The structure of this compound, determinated by single crystal X-ray diffraction, consists of anionic parallel [Zn(HPO4)Cl]? sheets alternating with thick slabs of organic molecules (C4H10N)+. These latters are linked to the anionic sheets through hydrogen bonds. Zn(HPO4)Cl[C4H10N] crystallizes in the monoclinic system and the space group C2/c (No. 9) with cell parameters a = 24,83(9), b = 9,258(5), c = 8.778(3), β = 110,45(4), Z = 8, V = 1891.0(14) Åt3, R = 0.045, and Rw = 0.07. Solid state 31P and 13C MAS NMR spectroscopies are in agreement with the X-ray structure. |
