Two new compound with formulas (tataH)2(pzdc).4H2O (1) ( tata = 2,4,6-triamino-1,3,5- triazine, pzdcH2 = pyrazine-2,3-dicarboxylic acid) and (BH)[Cr(pzdc)2]n (2) were synthesized. The BH ligand synthesized by the literature method. The products have been characterized by means of elemental analyses, NMR, and IR spectroscopies. The compound 1 crystallized in the triclinic system, space group P-1, with a = 7.0200 (14) Å, b = 9.763 (2) Å, c = 15.397 (3) Å,  = 101.06 (3), = 99.82 (3),  = 96.98 (3). In the crystal structure, an extensive series of O—H…O, O—H…N, N—H…O and N—H…N hydrogen bonds generates a three-dimensional framework with the hydrogen bonding involving most donor and acceptor centers. - stacking interactions are also observed between adjacent triazine rings, with centroid–centroid distances of 3.4994 (8) and 3.5922 (7) Å. Future efforts have been done to obtain good quality single crystals of compound 2 for better identification its molecular and crystal structure.
