Question:
(a) A 6-coordinate complex may be obtained by crystallizing anhydrous CaI2 from THF solution at 253 K. In contrast, when anhydrous BaI2 is crystallized from THF at 253 K, a 7-coordinate complex is isolated. Suggest structures for the two complexes, and comment on possible isomerism and factors that may favour one particular isomer in each case. Rationalize why CaI2 and BaI2 form complexes with THF that have different coordination numbers.
(b) Which of the following compounds are sparingly soluble in water, which are soluble without reaction, and which react with water: BaSO4, CaO, MgCO3, Mg(OH)2, SrH2, BeCl2, Mg(ClO4)2, CaF2, BaCl2, Ca(NO3)2? For the compounds that react with water, what are the products formed?
