Three-dimensional Ni/SnOx/C hybrid nanostructured arrays for lithium-ion microbattery anodes with enhanced areal capacity.

The areal capacity of lithium-ion microbatteies (LIMBs) can be potentially increased by adopting a three-dimensional (3D) architectured electrode. Herein, we report the novel 3D Ni/SnOx/C hybrid nanostructured arrays that were built directly on current collectors via a facile hydrothermal method followed by a calcination-reduction process. Branched SnO2 nanorods grew uniformly on Ni2(OH)2CO3 nanowall arrays, resulting in the formation of precursors with a 3D interconnected architecture.

The three-dimensional coordination network in poly[di-μ3-cyanido-μ5-[5-(pyridin-4-yl)tetrazolato]-tricopper(I)].

In the title three-dimensional tetrazolate-based coordination polymer, poly[bis(μ(3)-cyanido-κ(3)N:C:C)[μ(5)-5-(pyridin-4-yl)tetrazolato-κ(5)N:N':N'':N''':N'''']tricopper(I)], [Cu(3)(C(6)H(4)N(5))(CN)(2)](n), there are two types of coordinated Cu(I) atoms. One type exhibits a tetrahedral environment and the other, residing on a twofold axis, adopts a trigonal coordination environment. The closest Cu···Cu distance is only 2.

Benzene-1,3,5-tricarb-oxy-lic acid-5-(pyridin-1-ium-3-yl)-5H-1,2,3,4-tetra-zol-5-ide (1/1).

The asymmetric unit of the title compound, C(6)H(5)N(5)·C(9)H(6)O(6), comprises a full mol-ecule each of neutral trimesic acid (tma) and zwitterionic 5-(pyridin-1-ium-3-yl)-5H-1,2,3,4-tetra-zol-5-ide (ptz). The components are linked into a two-dimensional layer by a combination of O-H⋯O, O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds parallel to the (10[Formula: see text]) plane. Layers comprising alternating rows of tma and ptz are linked into a three-dimensional network by C-H⋯O and π-π inter-actions between tma and tetra-zolate rings [centroid-centroid distance = 3.
