27 Br 3.54 )(SeO 3 ) 4 Br 2 ), all but one exhibiting new complex layered or open-framework architectures, organized via the host-guest principle. Five of these structures contain only bivalent copper: three with well ordered 2D structures and completely filled atomic positions, two structures have 3D frameworks. The four remaining compounds contain both, Cu 2+ and Cu + , and comprise layers formed by edge-and vertex-sharing of oxocentered OCu 2+ 4-n Pb n tetrahedra decorated with SeO 3 2À and Br À anions. The interlayer spaces are filled by partially disordered Cu + -Br and Pb-Br associations. One remarkable feature of the latter group of compounds is the presence of tetrahedral (Cu 2+ ) 4 complexes with arrangements derivable from a kagome network. research papers Acta Cryst. (2018).

“…The bond length of Cu-Cl ranges from 2.2510(7) to 2.2771(6) Å with an average value of 2.264(7) Å, which is normal and similar to the counterparts found in the literature. [17][18][19][20][21] For the requirement of charge balance, 2,2'-dimethyl-2,2'-bipyridinium moieties must be protonated at the nitrogen atoms. The bond angle of Cl-Cu-Cl is in a range of 95.42(2)°-140.78(4)°.…”

A copper complex possessing two phases, i.e. α phase 2,2'-dimethyl-2,2'bipyridinium tetrachloro-copper(ii) α-CuCl 4 (N,N'-dimethyl-2,2'-H 2 bipy) (1) and β phase 2,2'-dimethyl-2,2'-bipyridinium tetrachloro-copper(ii) β-CuCl 4 (N,N'-dimethyl-2,2'-H 2 bipy) (2) has been synthesized via solvothermal reactions and structurally characterized by single-crystal X-ray diffraction. Complex 1 crystallizes in the space group C2/c of the monoclinic system with four formula units in a cell:

“…No volcano has been more prolific at producing unique minerals than the Tolbachik Volcano on Russia's Kamchatka peninsula (Pekov et al, 2018a). The synthesis of compounds by chemical vapour transport (CVT) using Cl 2 gas as a transport agent mimics the conditions under which many fumarole minerals are crystallized (Kovrugin et al, 2015(Kovrugin et al, , 2016, and CVT has been used to synthesize four new Cu-containing tellurites (Markovski et al, 2016;Zinyakhina et al, 2016). Te is generally enriched by up to four orders of magnitude in volcanic vents, with an average Te concentration of 50 p.p.m.…”

Crystals of the first synthetic copper tellurite arsenate, Cu II 5 (Te IV O 3 ) 2 (As V O 4 ) 2 [systematic name pentacopper(II) bis-oxotellurate(IV) bis-oxoarsenate(V)], were grown by the chemical vapour transport method and structurally determined using single-crystal X-ray diffraction. Cu II 5 (Te IV O 3 ) 2 (As V O 4 ) 2 possesses a novel structure type including a new topological arrangement of Cu II and O atoms. Cu II 5 (Te IV O 3 ) 2 (As V O 4 ) 2 is formed from a framework of two types of Jahn-Teller distorted [Cu II O 6 ] octahedra (one of which is considerably elongated) and [Cu II O 5 ] square pyramids, which are linked by edge-sharing to form chains and dimers and by corner-sharing to complete a three-dimensional framework. [As V O 4 ] tetrahedra and [Te IV O 5 ] polyhedra bridge the edges of channels along the a-axis direction, with void space remaining for the Te IV stereoactive 5s 2 lone pairs. A comparison is made between the crystal structure of Cu II 5 (Te IV O 3 ) 2 (As V O 4 ) 2 and those of known compounds and minerals, in particular fumarolitic Cu minerals.
