Abstract

Crystal structures of ten homoleptic platinum (II) complexes with N-methylthiourea, N,N-dimethylthiourea and 1-methyl-1H-imidazole-2(3H)-thione ligands and squarate, croconate, rhodizonate, terephthalic acid monocarboxylate and 1,4-naphthalene dicarboxylic acid monocarboxylate were determined by X-ray diffraction. The coordinated ligands display hydrogen bonding interactions with the counter anions, leading to the formation of a variety of different hydrogen bonded networks. The thiourea groups adopt different conformations around the metal centre, with a 1,2-alternate arrangement most frequently encountered. Discrete hydrogen bonds are the dominant interactions as a result of the disposition of the alkyl groups preventing the DDAA contacts usually displayed by thiourea ligands and carboxylates.
