Synthesis and crystal structure of aqua (2,2′-diamino-4,4′-bi-1,3-thiazole) (oxydiacetato)manganese(II) trihydrate
The title compound crystallizes in the triclinic space group with a = 7.194(3), b = 9.790(5), c = 12.492(1) Å, α = 82.407(16), = 86.664(15), = 89.882(15)°. The Mn(II) complex assumes distorted octahedral coordination geometry, formed by diaminobithiazole (DABT), an oxydiacetate dianion (ODA) and a water molecule. The tridentate ODA ion chelates to the Mn(II) atom in a meridional configuration. Each carboxyl group coordinates to the Mn(II) atom as a monodentate. Uncoordinated carboxyl oxygen atoms are involved in a hydrogen-bonding network. DABT chelates to the Mn(II) atom with a coplanar configuration. Coordinated water is hydrogen bonded to carboxyl groups of ODA of a neighboring complex to form supramolecular chains. A - stacking interaction involving thiazole rings occurs between adjacent supramolecular chains. A difference of 180 cm−1 between asymmetric and symmetric stretching vibrations of the carboxyl group corresponds to the extensive hydrogen-bonding network involving the carboxyl group.
