Summary:Tetracyanocalix[4]arene has been synthesized in a cone conformation and crystallized from solution in an orthorhombic system, space group P2 1 2 1 2 1 , with a = 13.7999(9) Å, b = 16.820(1) Å, c = 21.754(1) Å, D c = 1.218 g/cm 3 , Z = 4 (C 62 H 47 N 5 O 4 ). Refinement based on 11008 observed reflections yielded R1 = 0.042. Further crystallographic studies have revealed that this compound self-assembles into a one-dimensional coordination polymer in the presence of Ag + cation. This extended structure also crystallizes in an orthorhombic system, space group Cmca, with a = 17.770(1) Å, b = 31.498(2) Å, c = 23.107(2) Å, D c = 1.319 g/cm 3 , Z = 8 (C 63 H 52 AgCl 2 F 6 N 4 O 6 P). Refinement based on 7391 observed reflections yielded R1 = 0.109.
