Crystal structure of the yellow 1:2 molecular complex lumiflavin–bisnaphthalene-2,3-diol

Benes L. Trus, Joe L. Wells, Robert M. Johnstone, Charles J. Fritche Jun.  and Richard E. Marsh


In the first molecular complex of the physiologically active neutral form of isoalloxazine studied, lumiflavin–bisnaphthalene-2,3-diol, each flavin is sandwiched between two naphthalenediol molecules with extensive overlap but a moderately large (3·44 Å) spacing, indicating at most weak charge-transfer interaction and in agreement with the yellow colour of the complex, nearly the same as that of the parent lumiflavin.
