Self-Assembly of C-Methyl Calixresorcinarene with 5,5'-Bipyrimidine
The X-ray crystal structure of the complex formed between 5,5'-bipyrimidine and C-methylresorcinarene is described. The structure (C41H45N5O12) is triclinic with a = 12.8610(10), b = 13.0560(10), c = 13.6068(11)Å, α = 104.0730(10), β = 104.9260(10), γ = 111.6430(10)° and space group P-1. The structure reveals that the resorcinarene adopts a boat conformation and forms a three-dimensional network through hydrogen bonding to two water molecules and one dipyrimidine ligand. A single nitromethane molecule is included in the superstructure.
