The crystal structure of the natural 1,2,4-triazolate compound NaCu₂Cl₃[N₃C₂H₂]₂[NH₃]₂·4H₂O

Abstract

The crystal structure of a new natural compound NaCu

New Mineral Names

“…NH 3 and Clare additional ligands coordinating Cu 2+ . This structural motif is close to that of the associated phase Na 2 Cu 2 Cl 3 (N 3 C 2 H 2 ) 2 (NH 3 ) 2 •4H 2 O (Zubkova et al 2016). Chanabayaite is probably a transformational mineral formed as a result of leaching Na and one third of Cl and partial dehydration of this protophase.…”

Triazolite, NaCu2(N3C2H2)2(NH3)2Cl3·4H2O, a new mineral species containing 1,2,4-triazolate anion, from a guano deposit at Pabellón de Pica, Iquique Province, Chile

“…Triazolite is related structurally to chanabayaite (in part of the topology of the main structural unit containing zig-zag chains of the corner-sharing Cu-centred octahedra connected with isolated Cu-centred octahedra via 1,2,4-triazolate anions), which is a product of triazolite alteration as the result of dehydration and leaching of Na and a part of Cl (Zubkova et al ., 2016). Comparative data for triazolite and chanabayaite are given in Table 3.…”

“…A detailed crystal-structure description is given by Zubkova et al . (2016). The crystal structure of triazolite (Fig.…”

Bojarite, Cu3(N3C2H2)3(OH)Cl2⋅6H2O, a new mineral species with a microporous metal–organic framework from the guano deposit at Pabellón de Pica, Iquique Province, Chile

“…The new mineral species bojarite, Cu 3 (N 3 C 2 H 2 ) 3 (OH)Cl 2 ⋅6H 2 O, described in this paper is the ninth new mineral species discovered in guano deposits at Pabellón de Pica, after ammineite CuCl 2 (NH 3 ) 2 (Bojar et al , 2010), joanneumite Cu(C 3 N 3 O 3 H 2 ) 2 (NH 3 ) 2 (Bojar et al , 2017), chanabayaite Cu 2 (N 3 C 2 H 2 ) 2 Cl(NH 3 ,Cl,H 2 O,□) 4 (Chukanov et al , 2015a), möhnite (NH 4 )K 2 Na(SO 4 ) 2 (Chukanov et al , 2015b), shilovite Cu(NH 3 ) 4 (NO 3 ) 2 (Chukanov et al , 2015c), antipinite KNa 3 Cu 2 (C 2 O 4 ) 4 (Chukanov et al , 2015d), triazolite NaCu 2 (N 3 C 2 H 2 ) 2 (NH 3 ) 2 Cl 3 ⋅4H 2 O (Zubkova et al , 2016; Chukanov et al , 2018) and ammoniotinsleyite (NH 4 ) 2 Al 2 (PO 4 ) 2 (OH)⋅2H 2 O (Chukanov et al , 2020a). All these minerals, except antipinite, contain nitrogen, most of them contain organic groups, and in seven new minerals from this locality Cu 2+ is a species-defining component.…”
