Abstract

Two new isostructural open-framework zeotype transition metal borophosphate compounds, (H)0.5M1.25(H2O)1.5[BP2O8]·H2O (M = Co(II) and Mn(II)) were synthesized by mild hydrothermal method. The structure of compounds were characterized by single-crystal X-ray diffraction which have ordered, alternating, vertex-sharing BO4, PO4, and (MO4)OM(H2O)2 groups with hexagonal, P 61 2 2 (No 178) space group and unit cell parameters for Co a = 9.4960(6) Å, c = 15.6230(13) Å, for Mn a = 9.6547(12) Å, c = 15.791(3) Å, Z = 1 for both of them. TGA/DTA analysis, IR spectroscopy were used for characterization. Magnetic susceptibility measurements for both of the compound indicate strong antiferromagnetic interaction between metal centers.
