whereas compound 2 is a 2D coordination polymer. Interestingly, unlike to compounds 1 and 2, compound 3 possesses a distinctive structural feature having two crystallographically independent polymeric motifs (polymers, A and B) having two different dimensionality within the same crystal, i.e., coordination polymer A (CP-A) that forms a one-dimensional motif and coordination polymer B (CP-B), which has a
