Ion selective and complexing properties of 1,5-bis[2-(dioxyphosphoryl-4-methoxy)phenoxy]-3-oxapentane dihydrate H 4 M 2 · 2H 2 O ( I ) were described. X-ray diffraction analysis for compound I was performed. The crystals are orthorhombic, a = 7.9818(16) Å, b = 30.553(6) Å, c = 9.0559(17) Å, V = 2208.5(8) Å 3 , Z = 4, space group Pnma, R = 0.0500 over 1372 reflections with I > 2σ( I ). In I , the H 4 M 2 molecules are combined by hydrogen bonds (HB) with two crystallographically independent H 2 O(7) and H 2 O(8) molecules to give neutral H 4 M 2 · 2H 2 O aggregates. The HB between the phosphoryl and hydroxyl oxygen atoms of the aggregates and the donor O(7)-H…O(8) HB give rise to a layered structure. Conclusions about the Cu(H 2 M 2 ) compound structure were drawn based on the X-ray diffraction, DTA, and vibrational spectroscopy data.
