The 'boat' conformation of a resorcin[4]arene self-assembles as a 'T-shaped' building block in the solid state to form a linear 1D hydrogen-bonded array

Go-crystallization of C-methylcalix[4]resorcinarene 1 with 4-benzylpyridine (4-bzylpy) results in the formation of a linear 1D hydrogen-bonded array, 1(.)4(4-bzylpy) 2, in which the boat conformation of 1, in the form of an eightfold hydrogen bond donor, serves as a 'T-shaped' building block in the solid state. Crystal data for 2: triclinic, space group P (1) over bar, a = 14.992(1), b = 16.256(1), c = 16.365(1) Angstrom, alpha = 108.065 (1), beta = 96.140(1), gamma = 116.260(1)degrees, U = 3258.1(3) Angstrom(3), D-c = 1.25 g cm(-3), Mo-K alpha radiation (lambda = 0.71070 Angstrom) for Z = 2. Least-squares refinement based on 6045 reflections with I-net > 2.0 sigma(I-net) (out of 8151 unique reflections) led to a final value of R = 0.048.
