A new chiral layered zincophosphate [d-Co(en)3]Zn3(H(0.5)PO4)2(HPO4)2, designated ZnPO-CJ16, has been hydrothermally synthesized by using the optically pure chiral metal complex d-Co(en)3I3 as the template. It contains 4.6-net sheets which array in a helical fashion with an ABCDEF stacking sequence along the [001] direction. The chiral d-Co(en)3(3+) complex cations reside in the interlayer regions. Interestingly, there exist symmetrical O...H...O H-bonds between inorganic sheets, which results in a pseudo-three-dimensional open-framework structure stabilized by strong H-bonds. The crystal data are as follows: ZnPO-CJ16, [d-Co(en)3]Zn3(H(0.5)PO4)2(HPO4)2; M = 818.26; hexagonal; P6(5)22 (No. 179); a = 8.5832(12) A; c = 52.610(11) A; U = 3356.6(9) A(3); T = 293(2) K; Z = 6; R1 = 0.0415 (I > 2sigma(I)); wR2 = 0.1383 (all data); Flack parameter, 0.04(4).
一种新型手性层状磷酸锌[右旋-三（乙二胺）合钴（Ⅲ）]Zn3(H(0.5)PO4)2(HPO4)2，命名为ZnPO-CJ16，已通过使用光学纯的手性金属配合物右旋-三（乙二胺）合钴（Ⅲ）碘化物作为模板水热合成。它包含4.6-网层，这些层沿着[001]方向以ABCDEF堆积顺序呈螺旋状排列。手性右旋-三（乙二胺）合钴（Ⅲ）（3+）配合物阳离子位于层间区域。有趣的是，在无机层之间存在对称的O…H…O氢键，这导致了一种由强氢键稳定的伪三维开放框架结构。晶体数据如下：ZnPO-CJ16，[右旋-三（乙二胺）合钴（Ⅲ）]Zn3(H(0.5)PO4)2(HPO4)2；M = 818.26；六方晶系；P6(5)22（编号179）；a = 8.5832(12) Å；c = 52.610(11) Å；V = 3356.6(9) Å(3)；T = 293(2) K；Z = 6；R1 = 0.0415（I > 2σ(I)）；wR2 = 0.1383（所有数据）；Flack参数，0.04(4)。
