DEFINITION

Classification: 526/124.4

(under subclass 124.3) Subject matter wherein there is present (1) two different magnesium compounds neither of which contains a carbon to magnesium or a hydrogen to magnesium bond, or (2) a Group IA metal or nonmagnesium Group IIA metal compound, neither of which contains a bond between carbon or hydrogen and the Group IA or Group IIA metal.

(1) Note. An example of (1), supra, is the combination of MgCl2 and Mg(OC2[end subscrpt]H5)2[end subscrpt]. An example of (2), supra, is MgCl2[end subscrpt] KCl 6H2O.
