In situ ligand synthesis and construction of an unprecedented three-dimensional array with silver(i): a new approach to inorganic crystal engineering

Abstract
Reaction of 1,2-trans-(4-pyridyl)ethene with AgBF 4 results in the formation of a three-dimensional network based upon a cyclobutane-linked tetrapyridyl ligand, 1,2,3,4-tetrakis(4-pyridyl)cyclobutane, linked by Ag I ions; the in situ formation of the ligand represents a potential new direction for inorganic crystal engineering.
