Synthesis and crystal Structure of Aqua(diaminobithiazole (iminodiacetato)nickel(II) hydrate

摘要

(Crystals of the title compound, [(C_6H_6N_4S_2)(C_4H_5NO_4)(H_2O)Ni]-H_2O, consist of the Ni(II) complex and lattice water. The Ni(II) complex adopts a distorted octahedral coordination geometry formed by an iminodiacetate anion (IDA), a diaminobithiazole (DABT) and a coordinated water molecule. A twisted configuration of DABT is the distinguishing feature in the complex, the dihedral angle between thiazole rings of DABT being 20.04(8) deg. An aromatic stacking interaction occurs between thiazole rings from neighboring complex molecules, and is considered as the reason for the twisted configuration. The tridentate IDA dianion chelates to a Ni(II) atom in a facial configuration. A hydrogen bond network holds the complex molecules together to form a supramolecular structure.
