| Abstract: | A new metal borophosphate PbII4{Co2[B(OH)2P2O8](PO4)2}Cl ( 1 ), containing both Pb2+ cations and Cl– anions, was hydrothermally synthesized and characterized by powder X‐ray diffraction, ICP, TG/DTA, and FTIR spectroscopic analyses. The crystal structure determination from single‐crystal X‐ray diffraction reveals that compound 1 crystallizes in the trigonal space group R c (No. 167), a = 9.7513(7) Å, c = 91.060(13) Å, V = 7498.7(13) Å3 and Z = 18. Its structure features a new cobalt borophosphate layer {Co2[B(OH)2P2O8](PO4)2}7– built up from CoO5 square pyramids, [B(OH)2P2O8]5– borophosphate trimers and PO4 tetrahedra. Extra‐framework Pb2+ and Cl– ions are located at the vacancy of layers to achieve the charge neutrality of the framework. Magnetic measurements indicate that antiferromagnetic interactions exist between Co2+ ions with a negative Weiss constant of –20.3 K. |
