Until now, many attempts have been made on design and synthesis of ‎coordination compounds incorporating pyridine-2,6-dicarboxylic acid (dipicolinic ‎acid, pydcH2) [1]. This magic and simple organic compound can possess ‎multifarious behavior which has been alluded in the last papers [2].‎ The Cambridge Structural Database (CSD) analysis of dipicolinate coordination ‎modes, which has been performed in this paper, reveals behavior diversity of ‎this magic ligand to metal centers. In according to our study, 52 coordination ‎modes for pydcH2 exist in coordination compounds that lead to create versatile ‎structures and topologies. In this regard, 21 modes have been observed for ‎heteronuclear complexes. Among different effective factors, which can play role ‎in the abundance of modes, can be pointed to the existence capability of this ‎ligand as a neutral, mono-anion and/or di-anion states in the complex moieties. ‎ To pursuit our aim based on pydcH2 behavior[3-6], a new coordination ‎compound, [Cu2(pydc)4(µ-OH2)2(H2O)2K4].2H2O (1), has been synthesized and ‎characterized using X-ray crystal structure analysis. The performance of pydcH2 ‎in 1 and crystalline network were analyzed and were compared with the results ‎of CSD analysis. In this regard, Pydc2- illustrate three coordination modes in 1 ‎that one of them has not been reported, until now. ‎
