“…Polyamines, heterocycles and Schiff bases are important end-capping ligands [10][11][12] in this regard. Inorganic bridges like halides [13][14][15][16][17] and pseudohalides [18][19][20][21][22][23][24] have been extensively used for the isolation of such metal-organic frameworks. The larger-sized pseudohalide, dicyanamide (dca), is a versatile [21][22][23][24] bridging unit and may bind metal ion through terminal or bridges such as l 1,1, l 1,3, l 1,5 , l 1,1,5, l 1,3,5 , l 3,3,5 and l 1,3,3,5 motifs.…”
