Syntheses, Structure Characterizations and Fluorescent Properties of Two Reduced Molybdenum (V) Phosphates Functionalized by Zinc Coordination Complexes

摘要

Two new materials built from reduced molybdenum (V) phosphates as building blocks and zinc coordination complexes as linkers, (H3O)2[Zn(2,2′-bpy)]4[Zn(H2O)]2[Zn(HPO4)2 (PO4)6(MoO2)12(OH)6] · 6H2O (2,2′-bpy=2,2′-bpyridine) 1 and [Zn(phen)(H2O)2]2[Zn(phen) (H2O)]2[Zn(H2O)]2[Zn(HPO4)4 (PO4)4(MoO2)12 (OH)6] · 7H2O (phen=1,10-phenanthroline) 2, have been synthesized and characterized by elemental analyses, IR, TG, and single crystal X-ray diffraction. Compound 1 is a new 3-D structure which constructed from Zn[P4Mo6]2 dimers bonded together with [Zn(2,2′-bpy)] coordination complexes and [Zn(H2O)] fragments. In compound 2, the Zn[P4Mo6]2 dimeric units are linked by [Zn(phen)(H2O)] coordination complexes and [Zn(H2O)] fragments to form a new 2-D framework. The fluorescent activities of compounds 1 and 2 were reported. The crystal data for the two compounds are the following: 1, triclinic, P−1, a=13.036(3) Å, b=13.765(3) Å, c=14.459(3) Å, $alpha=64.69(3)^{circ}, beta=89.68(3)^{circ}, gamma=73.74(3)^{circ}$ , Z=1; 2, triclinic, P−1, a=12.708(3) Å, b=14.016(3) Å, c=14.646(3) Å, $alpha=78.18(3)^{circ}, beta=74.92(3)^{circ}, gamma=87.28(3)^{circ}$ , Z=1.
