X-ray crystallographic studies of hydrogen bonding in guanidinium containing salts

Abstract

Hydrogen bonding plays a central role in the formation of many crystal structures. A review of hydrogen bonding and crystallisation is presented in Chapter 1 along with details of X-ray crystallographic methods. In Chapter 2, small scale crystallisation and powder X-ray diffraction are developed as a method of screening for novel crystalline phases. This method has been used to examine guanidinium containing salts. Guanidinium was selected because of its hydrogen bond donating ability. Approximately ten previously unknown crystalline phases have been identified. The remainder of the thesis describes full single crystal analysis of three compounds, namely, (CH6N3)5[HP2Mo5O23]2.5H2O (Chapter 3), (CH6N3)+[FeCl4]- (Chapter 5) and [NH2SO3]¯ [CH6N3]+ (Chapter 4).
