The Organic Intercalates of HTiNbOs

Both parent compounds (KTiNbOs and HTiNbOs) and amine-intercalated HTiNb05 belong to the orthorhombic system a = 6.44, b = 3.78, c = 17.52 A for HTiNb05. The (TiNbOs) layer lies in the ab plane and intercalates amine in its protonated form. The interlayer distance c/2 expands on intercalation c = 9.02 A for ammonia, 22.96 A for methanamine, 26.78 A for ethanamine, 35.34 A for 1-propanamine, 36.82 A for 1-butanamine. 

The apparatus for the preparation of unstable metal hydrides such as FeTiH is shown in Figs. 1 and 2. It consists of a reactor and a pressure-vacuum manifold which is rated for pressures up to 68 atm and is constructed of stainless steel (300 series). The reactor is constructed of j tubing welded to a metal plug which forms the bottom closure. The top of the tube is welded to a O-ring connector (VCO Type, Cajon Co. 32550, Old South Rd., Cleveland, OH) which in turn is socket-welded to a X tube reducer. A sintered metal disc ( 5 pm

The hydride phases of FeTi are gray metal-like solids having essentially the same appearance as the dehydrided alloy. They are not pyrophoric at room temperature but ignition can occur at higher temperature. Thermodynamic and other properties of interest are summarized in Tables 1 and II.

Herein are described the preparations of the charge-transfer-type intercalation compound FeOCl (pyridine derivative), of grafted-type intercalation compounds FeO(OCH3) and Fe0(02C2H4)1/2 and of some organic intercalates of HTiNbOs.
