Two new isostructural open‐framework zeotype transition metal borophosphate compounds, (H) 0.5 M 1.25 (H 2 O) 1.5 [BP 2 O 8 ]·H 2 O (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 BO 4 , PO 4 , and (MO 4 )OM(H 2 O) 2 groups with hexagonal, P 6 1 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.
