title: 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 degrees and the pucker of the deoxyribose rings differ at the 3' and 5' ends.
