Description

The asymmetric unit of the title compound, C(24)H(24)N(2)O(4), comprises two crystallographically independent mol-ecules A and B. The dihedral angles between the central dimethyl-substituted benzene ring and the two outer benzene rings are 49.5 (1) and 5.06 (11)° in mol-ecule A, and 42.55 (8) and 5.77 (9)° in mol-ecule B. In each mol-ecule, two strong intra-molecular O-H⋯N hydrogen bonds generate two S(6) ring motifs. The crystal structure is further stabilized by inter-molecular π-π [centroid-centroid distances of 3.591 (1)-3.876 (1) Å] inter-actions.

Translated Description (French)

L'unité asymétrique du composé du titre, C(24)H(24)N(2)O(4), comprend deux mol-écules A et B cristallographiquementindépendantes. Les angles diédriques entre le cycle benzénique central substitué par un groupe diméthyle et les deux cycles benzéniques externes sont de 49,5 (1) et 5,06 (11) ° dans la mol-écule A et de 42,55 (8) et 5,77 (9) ° dans la mol-écule B. Dans chaque mol-écule, deux fortes liaisons hydrogènes intra-moléculairesO-H) N génèrent deux motifs cycliques S(6). La structure cristalline est en outre stabilisée par des interactions intermoléculaires π-π [distances centroïde-centroïde de 3,591 (1) -3,876 (1) Å].

Translated Description (Spanish)

La unidad asimétrica del compuesto del título, C(24)H(24)N(2)O(4), comprende dos moléculas A y B cristalográficamenteindependientes. Los ángulos diedros entre el anillo central de benceno sustituido con dimetilo y los dos anillos exteriores de benceno son 49,5 (1) y 5,06 (11) ° en la secuencia molar A, y 42,55 (8) y 5,77 (9) ° en la secuencia molar B. En cada mol-ecuela, dos fuertes enlaces de hidrógeno O-H) N intramoleculares generan dos motivos de anillo S(6). La estructura cristalina se estabiliza aún más mediante interacciones intermoleculares π-π [distancias centroide-centroide de 3.591 (1) -3.876 (1) Å].
