The final R=0.047 for 1736 independent reflections. Planar tetracyanoquinodimethane(TCNQ) stacks along b axis with the molecular planes nearly parallel to each other, and mixed with 2N-methylcinnoline(2N-MCi). The separations between TCNQs are 3.212A and 3.321 A. Two overlap types are quite different. One is of ring external bond overlap, while the other has hardly direct overlap. This feature of 2N-MCiTCNQ2 stacking is used to explain the semiconducting character of the title compound.
