3,3'-Dihy-droxy-6,6'-bis-(hy-droxy-meth-yl)-2,2'-(pentane-1,1-di-yl)di-4H-pyran-4-one.

ABSTRACT: In the title mol-ecule, C(17)H(20)O(8), the two pyran rings form a dihedral angle of 61.2?(2)°. The two hy-droxy-methyl groups are each disordered over two sets of sites in a 0.764?(3):0.236?(3) ratio. In the crystal, O-H?O hydrogen bonds link the mol-ecules into layers parallel to the ac plane.

Project description:In the title compound, a new macrocyclic metal complex, [Ag(NO(3))(C(21)H(15)N(3)O(4))], all non-H atoms are in a close-to-planar geometry (except for the nitrate anion), with a maximum out-of-plane deviation of 0.327 (6) Å for a pyridine C atom. The dihedral angle between the least-squares plane through the [3,3'-dihy-droxy-3,3'-bis-(pyridin-3-yl)-1,1'-(pyridine-2,6-di-yl)dipropan-1-one]silver(I) fragment and the nitrate anion is 31.29 (13)°. The mol-ecular structure is stabilized by several inter- and intra-molecular O-H⋯O and C-H⋯O hydrogen bonds. The Ag(I) atom is coordinated by two pyridine N atoms and two O atoms of the nitrate anion in a geometry intermediate between tetrahedral and square-planar.
