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)
Tin-Tin Kyrano that stereotypes are common but "handled with some sensitivity – all except for Tin-Tin, a literal China doll". Kate Hunt of the University of Glasgow, author of a study of the series' presentation of tobacco smoking, observes that in marked contrast with prolific smokers such as Penelope, Tin-Tin is "incongruously" and "inconsistently" seen with a cigarette in only one episode ("The End of the Road"). She writes that the character occupies a socially-ambiguous position within her home environment, appearing variously as "adopted daughter, secretary, and occasional member of the International Rescue team".
