Molecular structure of a double helical DNA fragment intercalator complex between deoxy CpG and a terpyridine platinum compound

Abstract
The crystal structure of a complex containing deoxy CpG and a terpyridine platinum compound (TPH) shows a DNA double helical fragment with TPH intercalated between two Watson–Crick GC base pairs. The DNA unwinding angle is 23° and the pucker of the deoxyribose rings differ at the 3′ and 5′ ends.
