چکیده
The title compound, C(14)H(18)O(4), was obtained unintentionally as the major product of an attempted synthesis of (E,E)-2,5-bis-[2-(2,4,6-trimeth-oxy-phen-yl)ethen-yl]pyrazine. The crystal packing features layers based on two weak C-H⋯O hydrogen bonds involving the O atom of the carbonyl group and two O(meth-oxy)⋯C(meth-oxy) inter-actions [3.109 (2) Å]. The sheets are inter-connected via meth-oxy-meth-oxy dimers and C-H⋯π inter-actions.

The structure of the title compound, [Mg(2)(C(4)H(9))(C(14)H(18)NO)(3)], contains two Mg atoms bridged by two μ(2)-O atoms from two of the three ketiminate ligands, while the third ketiminate is strictly chelating to one of the Mg atoms, which is thereby five-coordinate. In place of a chelating ligand, the second Mg atom is ligated by a single terminal n-butyl group and thus is four-coordinate....

In the title heteroaryl chalcone derivative, C(16)H(16)O(5), the dihedral angle between the furan and benzene rings is 14.45 (6)°. The three meth-oxy groups are almost coplanar with their attached benzene ring [C-C-O-C torsion angles = 2.07 (17), -5.04 (17) and 2.85 (16)°]. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, adjacent mol-ecules are linked into X-shaped chains along t...

The title heteroaryl chalcone derivative, C(17)H(17)NO(4), is a condensation product of 2-acetyl-pyridine and 2,4,6-trimeth-oxy-benzaldehyde. The mol-ecule is roughly planar, the dihedral angle between the pyridine and benzene rings being 5.51 (10)°. All the three meth-oxy groups are almost co-planar with the bound benzene ring [r.m.s. deviation of 0.0306 (2) Å]. A weak C-H⋯O intra-molecular in...
