(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. Symmetry codes: (i) x − [{1\over 2}], −y + 1, z − [{1\over 2}]; (ii) −x + [{1\over 2}], −y + 1, z − [{1\over 2}]; (iv) x, y + 1, z; (v) −x, y + 1, z; (vi) −x + [{1\over 2}], −y + 1, z + [{1\over 2}]; (vii) −x + [{1\over 2}], −y, z − [{1\over 2}].
