- This hexagonal structure has been superseded by the monoclinic structure of (Ilyushin, 1981). We present it here for historical interest.
- We were unable to procure the original reference, so we use the data provided by (Gottfried, 1937).
- Four of the (6g) sites are randomly occupied by water molecules.
- (Gottfried, 1937) originally gave the Strukturbericht designation $S3_{4}$ to chabazite, but (Gottfried, 1940) gave it to this structure of catapleiite. We distinguish between the two cases by using $S3_{4}$(I) to designate chabazite and $S3_{4}$(II) to designate catapleiite.
