Abstract:
The structure of (1-methoxy-8-naphthyllithium.THF)(2), (2.THF)(2), determined by single-crystal X-ray diffraction (crystal data: monoclinic, a = 8.1816 (5), b = 21.9649 (14), and c = 8.2345 (3) A, beta = 117.969 (3) degrees; V = 1306.97 (12) A(3); space group P2(1)/n; Z = 4) reveals a centrosymmetrical dimer with a twist angle of about 63 degrees between the naphthyl rings and the Li-C(ipso)-Li plane, representing an intermediate between perpendicular and planar tetracoordinated C(ipso). NMR studies at low temperature indicate that 2 is dimeric in THF-d(8) solution under these conditions.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
