Abstract
A new basic copper sulfamate Cu3(OH)5[SO3(NH2)] of the anthropogene origin from the oxidation zone of the Murzinskoe gold deposit (Altai Krai, Russia) has been characterized with XRD and IR spectroscopy. This compound has not natural or synthetic analogue and represents a novel structure type. It is monoclinic, space group P21/c, a = 7.5817(4); b = 5.9823(3); c = 17.0084(8) Å; = 99.140(5)°; V = 761.63(7) Å3 ; Z = 4. The crystal structure of this sulfamate (R = 4.91%) is based on the distorted brucite-type layers built by Cu2+-centred octahedra of three different types: CuO2(OH)4, Cu(OH)6 and CuO(OH)5. Isolated from each other SO3NH2 tetrahedra are linked to the layers from both sides. The neighboring heteropolyhedral layers formed by Cu-centred octahedra and SO3NH2 tetrahedra are connected via the system of hydrogen bonds.
