(a) Situation of four (ccnm)− anions around the polyhedral stack, which is orthogonal to the drawing plane. (b) View of the framework down the b-axis direction, showing the principal coordination and hydrogen-bond interactions. (c) Topology of the metal–anion connectivity, in the form of a binodal heterocoordinated net with trigonal–prismatic [Ba2+] and trigonal [μ3-(ccnm)−] nodes, which are indicated in blue and red, respectively.
