Tin(II) chloride dihydrate is also three-coordinate, with one water coordinated on to the tin, and a second water coordinated to the first. The main part of the molecule stacks into double layers in the crystal lattice, with the "second" water sandwiched between the layers. Tin(II) chloride can dissolve in less than its own mass of water without apparent decomposition, but as the solution is diluted, hydrolysis occurs to form an insoluble basic salt: Therefore, if clear solutions of tin(II) chloride are to be used, it must be dissolved in hydrochloric acid (typically of the same or greater molarity as the stannous chloride)
Arena Naucalpan 15th Anniversary Show Anniversary Show is the fourth oldest still ongoing annual show in professional wrestling, the only annual shows that older are the Consejo Mundial de Lucha Libre Anniversary Shows (started in 1934), the Arena Coliseo Anniversary Show (first held in 1943), and the "Aniversario de Arena México" (first held in 1957). The Arena Naucalpan 15th Anniversary Show was organized by Alfonso Moreno and featured a large number of wrestlers from Consejo Mundial de Lucha Libre (CMLL), who allowed Moreno to book their wrestlers on a regular basis and in this case also sanctioned a match for the CMLL World Middleweight Championship.
