(E)-3-[(2-Hy-droxy-3-meth-oxy-benzyl-idene)amino]-benzoic acid.

In the title compound, C(15)H(13)NO(4), the dihedral angle between the substituted benzene rings is 9.9 (8)°. Part of the mol-ecule (the salicylaldimine segment) is disordered over two sets of sites, with a refined site-occupancy ratio of 0.

Aqua-chloridobis(2-eth-oxy-6-formyl-phenolato-κO,O)chromium(III) acetonitrile hemisolvate.

In the mononuclear complex mol-ecule of the title compound, [Cr(C(9)H(9)O(3))(2)Cl(H(2)O)]·0.5CH(3)CN, the Cr(III) atom displays an elongated octa-hedral coordination geometry. The dihedral angle between the benzene rings is 12.
