Two new open-framework zinc phosphites, [M(C{sub 6}N{sub 4}H{sub 18})][Zn{sub 3}(HPO{sub 3}){sub 4}] (M=Ni, Co), have been prepared under hydrothermal conditions. Single-crystal X-ray diffraction analysis shows that [Ni(C{sub 6}N{sub 4}H{sub 18})][Zn{sub 3}(HPO{sub 3}){sub 4}] (1) and [Co(C{sub 6}N{sub 4}H{sub 18})][Zn{sub 3}(HPO{sub 3}){sub 4}] (2) are isostructural and both crystallize in the monoclinic space group C2/c with a=15.325(3)A, b=9.792(2)A, c=14.514(3)A, {beta}=109.83(3){sup o}, V=2048.8(7)A{sup 3},Z=4, R{sub 1}=0.0408 (I>2{sigma}(I)), and wR{sub 2}=0.1104 (all data) for 1, and a=15.277(2)A, b=9.8831(13)A, c=14.534(2)A, {beta}=109.328(2){sup o}, V=2070.7(5)A{sup 3},Z=4, R{sub 1}=0.0380 (I>2{sigma}(I)), and wR{sub 2}=0.1093 (all data) for 2. The structures of 1 and 2 are built up from strictly alternating ZnO{sub 4} tetrahedra and HPO{sub 3} pseudo-pyramids linked through oxygen vertices to form the three-dimensional (3-D) open-frameworks with multi-directional intersecting 12-membered ring (12-MR) channels. The M(TETA) (M=Ni, Co) complexes self-assembled under hydrothermal system connect with the inorganic host via M-O-P linkages and interact with inorganic framework through weak H-bonds. The two compounds show intense photoluminescence upon photoexcitation at 235nm.
