A Layered Zinc Phoshate ,[C_6N_4H_(22][Zn_6(PO_4)_4(HPO_4)_2] Formed by One-Dimensional Tubes

摘要

An open-framework zinc phosphate,[C_6N_4H_(22)][Zn_6(PO_4)_4(HPO_4)_2] (I),with alternating inorganic and organic layers has been synthesized hydrothermallyfrom a starting mixture of ZnO,HCl,H_3PO_4,H_2C_2O_4,and triethylenetertramine.Single-crystal data for I:monoclinic,space group =P2_1/c (No.14),#alpha#=9.881(1),b=16.857(1),c=8.086(1) A,#beta#=96.7(1) V-1370.8(1) A~3,Z=2,R_1=0.06,and wR_2=0.13 [1408 observed reflections with I>2#delta#(I)].The structure of I comprises a network of ZnO_4,PO_4,and PO_3(OH) tetrahedra forming one-dimensional tubes.The tubes,in turn,are linked via oxygen atoms forming macroanionic inorganic layers witheight-mem-bered apertures.The one-dimensionaltube-like architecture in I is a novel feature worthy of note.
