Özet

H(2)bpe(H2PO3)(2) (1) and H(2)bpe(H2PO4)(2) center dot H2O (2) (H(2)bpe = ethene-trans-1,2-bis(4-pyridinium), H2PO3 = dihydrogenphosphite, and H2PO0 = dihydrogenphosphate) have been prepared and structurally characterized. In compound 1, the dihydrogenphosphite anions form dimers, with a P center dot center dot center dot P distance of 4.2073(7) angstrom, by two O-H center dot center dot center dot H hydrogen bonds, and the dimeric dihydrogenphosphite units interact with the H(2)bpe cations by way of N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds, resulting in a one-dimensional chain. The chains are held together by C-H center dot center dot center dot O interactions. In compound 2, the phosphate ions are connected by O-H center dot center dot center dot O hydrogen bonds into an unusual 2D square grid-type framework with P center dot center dot center dot P separations ranging from 4.7533(7) to 4.9506(8) angstrom. The H(2)bpe cations crosslink the dihydrogen phosphate layers by N-H center dot center dot center dot O hydrogen bonds, forming a three-dimensional supramolecular network with channels. The water molecules in compound 2 occupy these channels and make O-H center dot center dot center dot O bonds to adjacent phosphate O atoms and also O-H center dot center dot center dot O bonds to the next water O atom in the channel.
