Crystal structures of ethyl 6-(4-methyl­phen­yl)-4-oxo-4H-chromene-2-carboxyl­ate and ethyl 6-(4-fluoro­phen­yl)-4-oxo-4H-chromene-2-carboxyl­ate

The crystal structures of two chromone derivatives, viz. ethyl 6-(4-methyl­phen­yl)-4-oxo-4H-chromene-2-carboxyl­ate, C(19)H(16)O(4), (1), and ethyl 6-(4-fluoro­phen­yl)-4-oxo-4H-chromene-2-carboxyl­ate C(18)H(13)FO(4), (2), have been determined: (1) crystallizes with two mol­ecules in the asymmetri...
