• Molecular structure of [2.2](1,4)naphthalenophane containing 7,7,8,8-tetracyanoquinodimethan moiety as an electron acceptor has been determined by means of X-ray diffraction. Crystals belong to monoclinic system, space group Cc with four molecules per unit-cell; <I>a</I>=9.770(1), <I>b</I>=15.176(2), <I>c</I>=13.299(2) Å, β=98.43(1)°. The structure was established by the direct method and refined by the full-matrix least-squares to <I>R</I>=0.035 for 1217 non-zero reflections. The [2.2]paracyclophane skeleton has the usual structure; a half of the naphthalene moiety has a boat-form, the six-membered ring of the TCNQ, moiety also has a boat-form, and two C(CN)<SUB>2</SUB> portions in the TCNQ, moiety are bent out and slightly twisted from the six-membered ring. The other half of the naphthalene ring free from the bridging is planar and are slightly bent out from the [2.2]paracyclophane skeleton.
