3,4,5-Trimeth-oxy-phenol.

ABSTRACT: The asymmetric unit of the title compound, C(9)H(12)O(4), consists of two crystallographically independent mol-ecules with similar conformations: essentially planar [r.m.s deviations for C(6)O(4) = 0.0057 and 0.0137?Å] except for the central meth-oxy-methyl group [C-C-O-C torsion angles = 83.3?(2) and 83.9?(2)°]. In the crystal, O-H?O hydrogen bonds link the mol-ecules, generating supra-molecular chains along the b axis.The three-dimensional crystal structure is stabilized by C-H?O and C-H?? inter-actions.

Project description:In the asymmetric unit of the title compound, C(18)H(20)N(2)O(5), there are two crystallographic independent mol-ecules.

In the crystal, mol-ecules are linked by N-H?O hydrogen bonds and weak C-H?O inter-actions into tapes along the b axis. C-H?? inter-actions are also present.
