Diaqua-bis-(2-oxo-2H-chromene-3-carboxyl-ato-?O,O)manganese(II).

ABSTRACT: In the title compound, [Mn(C(10)H(5)O(4))(2)(H(2)O)(2)], the Mn(II) atom lies on a crystallographic inversion center and is six-coordinated by two O atoms from water mol-ecules in the axial positions and four O atoms from two deprotonated coumarin-3-carb-oxy-lic acid ligands in the equatorial plane. The overall coordination geometry is slightly distorted octa-hedral. The Mn-O bond distances vary between 2.0931?(12) and 2.2315?(13)?Å. O-H?O hydrogen bonds between the H atoms of coordinated water mol-ecules and the O atoms of the carboxyl-ate groups link the complex mol-ecules into two-dimensional layers parallel to the ab plane.

Diaqua-bis-(pyridine-2-carboxyl-ato-κN,O)manganese(II) dimethyl-formamide hemisolvate.

Project description:There are two crystallographically independent complex mol-ecules with very similar geometries in the unit cell of the title compound, [Mn(C(6)H(4)NO(2))(2)(H(2)O)(2)]·0.5C(3)H(7)NO. The central ion is situated in a distorted octa-hedral environment of two N- and four O-donor atoms from two pyridine-2-carboxyl-ate ligands and two cis-disposed water mol-ecules. The carboxyl-ate ligands are coordinated in a chelate fashion with the formation of two five-membered rings. In the crystal, the complex mol-ecules are connected by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the uncoordinated carboxyl-ate O atoms, thus forming hydrogen-bonded walls disposed perpendicularly to the bc plane.

Project description:The title compound, C(20)H(24)O(4), was synthesized from the reaction of 2-oxo-2H-chromene-3-acyl chloride and menthol. The mean plane of the ester group and that of the four essentially planar (maximum deviation 0.0112?Å) C atoms of the chair-form cyclo-hexyl ring form dihedral angles of 43.8?(3) ° and 81.8?(1)°, respectively, with the mean plane of the coumarin ring system. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds connect the mol-ecules into a two-dimensional network.
