摘要: 2,9-Dimethyl-1,10-phenanthroline (dmp) intercalates into α-Zr(HPO4)2. (2EtOH) to form α-Zr(HPO4)2 (dmp)0.50. 2.5H2O at maximum uptake, 25°C. This lamellar composite has an interlayer distance of 14.60(5) A, which changes little - 13.58(5) A when the pseudo-zeolitic water is lost. An almost vertical orientation dmp between phosphate layers proposed, as was found previously for unsubstituted phenanthroline analogue. When material exchanged with Co2+, Ni2+, and Cu2+, under conditions such that [M] : [L] = 1:1 there partial elution dmp, giving rise materials formulation α-ZrH1.3M(OH2)0.35(dmp)0.35(PO4)2·nH2O, no change in distance. Spectroscopic evidence formation dimers intercalated described.
