Low-Dimensional Hybrid Copper Halides with Novel D6R Cu₆I₆ Cores

Abstract

Two low-dimensional hybrid copper halides, (2,2'-bipy)Cu(3)I(3) (1) and (2,2'-bipy)Cu(4)I(4) (2) (2,2'-bipy = 2,2'-bipyridine), with novel D6R (double six-membered rings) Cu(6)I(6) cores were synthesized by hydro(solvo)thermal reactions and characterized by single-crystal X-ray diffraction.

Synthesis, Crystal Structures and Photoluminescent Properties of Three Novel Cadmium(II) Compounds Constructed from 5‐Sulfoisophthalic Acid (H3SIP)

“…[5][6][7] Consequently, a wide variety of coordination architectures with interesting structures and desired properties have been prepared through judicious choice of organic ligands and metal ions. [8][9][10][11] Recently, 5-sulfoisophthalic acid (H 3 SIP) has been successfully used to investigate the lanthanide contraction effect [12] and the coordination polymer chemistry of a main group metal (Pb 2+ ), [13] because of its multiple coordinating modes and the sensitivity of the sulfonate group to the surrounding chemical environment. In this contribution, SIP will serve as a probe to examine the coordination polymer chemistry of the late transition metal Cd 2+ .…”

Synthesis, structure, and luminescent property of the first mixed-valence Cu-halide complex constructed from novel D6R Cu6Cl6 cores

“…As we all known, the structure of the hexanuclear Cu 6 Cl 6 cores is similar to that of the double six-membered rings (D6R, hexagonal prisms) found in zeolite. This kind of building unit is seldom found in Cuhalides complexes [24]. To our knowledge, complex 1 is the first Cu-halides complexes constructed from Cu 6 Cl 6 cores and mixed-valence Cu ions.…”

“…These include single molecular to chain-like (one-dimensional), layered (two-dimensional), threedimensional extended system. To the best of our knowledge, the basic Cu(I)-halide skeleton of these complexes generally exhibits several structural motifs: square dimmers, cubane tetramers, double-stranded ladders, and hexagonal grid chains as shown in Scheme 1 [24].…”

[Cu2Br2(BPP)]n (BPP=1,3-bis(4-pyridyl)propane): A luminescent 2-D inorganic–organic hybrid coordination network with 1-D copper (I) chains bridged by trans-Br atoms

“…Several of them in various dimensionality including 1-D chain-like, 2-D layered and 3-D extended structures have been synthesized and characterized [1][2][3][4][5][6]. As a summary of the reported structures, the basic structural skeletons of copper (I) halides (CuX) are listed in Scheme 1.…”

“…They are: (a) square (rhomboid) dimer; (b) cubane tetramer; (c) diamondoid tetramer; (d) zigzag chain; (e) double-stranded ladder and (f) hexagonal grid chain, respectively. Besides their intriguing topology [1][2][3][4][5], copper (I) halide complexes have attracted wide interest for their rich photophysical properties [7][8][9][10]. The presence of direct CuÁ Á ÁCu interactions has been proved to be one of the crucial causes to the luminescent properties in such species [7].…”
