The synthesis and structural characterization of the Nsubstituted bis(diphenylphosphanyl)amine Ph2PN(R)PPh2 (R = n-propyl, 1) is reported. Single crystals of 1grown from dichloromethane/acetonitrile have been analyzed by Xray crystallography. The crystallographic study revealed that the diphenylphosphanyl groups in 1are staggered relative to the PNP backbone as observed for other closely related molecules.

Single crystals of d(CTCCTSCCGCGCG)·d(CGCGCGGAG) have been grown by the vapor-diffusion method using 2-methyl-2,4-pentanediol as a precipitant. The crystals are tetragonal, space group P42, with unit-cell parameters a = b = 53.8, c = 43.1 Å, and diffract to 1.8 Å resolution at a synchrotron X-ray beamline. In the crystal, the asymmetric unit contains one copy of the construct. The two halves of the structure are related by non-crystallographic twofold symmetry. These observations are consistent with the conclusion that the sequences of the 12-mer and 9-mer oligonucleotides form a duplex DNA at one end and a triplex DNA at the other end.

Controlled formation of catalytically-relevant states within crystals of complex metalloenzymes represents a significant challenge to structure-function studies. Here we show how electrochemical control over single crystals of [NiFe] hydrogenase 1...
