The framework is further stabilized by classical O-H⋯O hydrogen bonds involving the coordinating water mol-ecules and the sulfate groups, and by N-H⋯O hydrogen bonds between the disordered tetra-zine NH groups and sulfate oxygen atom, along with C-H⋯π and π-π stacking [centroid-to-centroid separation = 3.5954 (15) Å] inter-actions between parallel pyrimidine rings of the H2bmtz ligand.In the central fused ring system of the title compound, C51H42O5, all of the five-membered rings are in an envelope conformation.
