FIGURE 2.

Views of two‐dimensional supramolecular structure of 1 formed parallel to the (50‐4) plane. Two symmetry‐independent 1D chains constructed along the b axis through the N—H … O (black dashed lines, Table 2) classical hydrogen bonds building the $R_2^2\left(8\right)$ motif rings are connected together by the C—H … C (orange dashed lines, Table 2) and C—H … π (red dashed lines, Table 2) interactions. Different colors have been shown for symmetrically independent molecules. The “P(O)NH” segments involving the N—H … O classical hydrogen bonds are depicted as “ball and stick” and cobalt metal centers are shown as violet colored big balls
