摘要：

A new polymorph of 3,4-dihydro-2-methoxy-2-methyl-4-phenyl-2H,5H-pyrano[3,2-c]chromen-2-one (pyranocoumarin) was studied by X-ray diffraction. The crystallographic parameters of the structure of C(20)H(18)O(4)areM= 322.34, sp. gr.C2/c,a= 23.542(1) angstrom,b= 8.4938(3) angstrom,c= 19.7804(8) angstrom, beta = 125.977(3)degrees,Z= 8.
