Synthesis and Crystal Structure of (Z)-1,2,5-Trimethyl-3-Pyrrolylmethylidene (Isop ropy lidene)-Succinic Anh ydride

Abstract

Abstract: The title compound has been synthesized and the crystal structure has been determined by single-crystal X-ray diffraction techniques. M_t=259, triclinic crystal, space group P1 with a=8.116(1)Å,6=8.903(2)Å, c=9.995(2)Å, a=86.96(1)°, β=74.27(1)°, V=74.35(1)°, V=669.1(2)Å³and Z=2. The structure was solved by direct methods and Fourier Synthesis and refined by block-matrix least square method. The final result gives R=0.060 for 1196 independent reflections with |F|/σ(|F|)≥2.5. The compound is a (Z)-coplane molecule.

Key words: Heterofulgide, Crystal structure, Planar molecule
