The inclusion of bithiophenedicarboxylate (btDC) in La(III)[15-MCCu,N,L-phenylalaninehydroximate-5] hosts (LaMC) unexpectedly results in a clathratocomplex with a completely disrupted hydrophobic cavity. Structures best formulated as {(LaMC)2(μ2-O)} are formed that dimerize across the hydrophilic parts. This dimer appears stabilized by 5 phenyl-DMF-phenyl interactions and 10 DMFamine hydrogen bonds. Electrospray ionization mass spectrometry reveals the presence of 2 : 2 LaMC-btDC complexes in solution. In the solid state, both cis- and trans-bithiophene dicarboxylate guests bridge the > 17 Å distance between LaMC hydrophobic faces. The resulting solid has over 50% void space, suggesting guest-length and solvent considerations can predictably lead to the formation of open LaMC coordination frameworks or close-packed molecular compartments.

Three new N-phosphinoyl-substituted aminomethanephosphonic acids have been synthesized and characterized: dimethylphosphinoylmethyl-imino-bis(methanephosphonic acid) (1), [3-(dimethylphosphinoyl)-propyl]-imino-bis(methanephosphonic acid) (2), and N-benzyl-Ndimethylphosphinoylmethyl- aminomethanephosphonic acid (3). The latter was isolated as a hydrochloride 3 ・ HCl. The acids have been prepared via Moedritzer-Irani reaction from the corresponding dimethylphosphinoyl-substituted primary and secondary aliphatic amines. Their structures have been confirmed by elemental analysis, IR, 1H, 31P{1H}, 13C{1H} NMR spectroscopy, electrospray ionization mass spectrometry, and single-crystal X-ray diffraction.
