Crystal Structures and Selected Properties of CoII Containing Thiostannates prepared by a New Room Temperature Route
The room temperature reaction of Na4Sn2S6¡¤5H2O with CoCl2¡¤6H2O and 2-(aminomethyl)pyridine (2-AMP) or trans-1,2-diamino-cyclohexane (DACH) leads to crystallization of two compounds with the compositions [Co(2-(aminomethyl)pyridine)3]2 Sn2S6¡¤10H2O (1) and [Co(trans-1,2-diaminocyclohexane)3]2Sn2S6¡¤8H2O (2). In both compounds [Sn2S6]4? anions are present that are charge balanced each by two Co2+ centered complexes. Each of the two CoII cations are sixfold coordinated by six N atoms of three 2-AMP or DACH ligands within slightly distorted octahedra. In compound 1, the two complexes are linked by one [Sn2S6]4? anion via strong N?H¡¤¡¤¡¤S hydrogen bonds into centrosymmetric charge neutral trimeric units, that are further linked by weak C?H¡¤¡¤¡¤S and N?H¡¤¡¤¡¤S hydrogen bonds into chains that are directed along the a axis. These chains are further joined by N?H¡¤¡¤¡¤O and O?H¡¤¡¤¡¤O hydrogen bonds into a 3D network, with the H2O molecules forming chains along the b axis. The crystal structure of 2 is similar to that of 1 featuring trimeric units which are also linked into chains. Between the chains water molecules are embedded that link the chains into a 3D network. Upon heating 2 in a thermobalance the water and ligand molecules are removed in discrete steps, indicating that compounds with more condensed thiostannate networks will form.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1436-59-5 is helpful to your research., Reference of 1436-59-5
