“…These include a few carboxylate scaffold supported Cu(I) dimers (see X ) . This scaffolding of Cu 2 (μ 2 -CO) by carboxylate has been used to produce a pair of interesting five-coordinate 2-D polymers, [Cu 2 (μ 2 -CO)(nic) 2 ] ( X ; nic = isonicotinoate, nicotinoate) . Homonuclear bridging Cu(I) carbonyls are also found in several clusters containing Fe and Mo ( XI ) .…”

The coordination chemistry of copper(I) carbonyls and cyano complexes is reviewed. Primary attention is focused structural chemistry, including coordination behavior, bridging modes, network formation, flexible coordination number, and reversible ligand binding. Additional coverage of infrared spectroscopy and orbital interactions in carbonyl and cyanide bonding, and photophysical behavior of metal cyano complexes is also included. BRIEF The coordination chemistry of copper(I) carbonyls and cyanide complexes is reviewed.

“…These different coordination sites result in a rich phase behavior of MOFs based on copper nodes and INA linkers: molecular clusters with embedded water; [31] 1D chains with hydrogen bonds in between; [32,33] 2D, [34] and 3D networks with empty pores [35] and with pores accommodating water or alcohols. [35][36][37] The copper nodes can be either a single atom, [35] copper paddlewheels formed with four carboxylates, [38,39] or a combination of both. [40][41][42] In addition, structures containing complex nodes [43] and even copperoxo chains [44] have been observed.…”

tion of homogeneous films onto solid supports. [9] The presence of a surface during framework formation can strongly influence the crystallization process, even inducing the formation of unknown crystal phases. Such unique polymorphs also appear in thin films of purely organic or inorganic compounds [10] and are commonly referred to as substrate-induced polymorphs or thin-film phases. [11] Detailed knowledge of these crystal structures is essential since thin-film phases can have considerably different properties than bulk polymorphs. [12] MOF thin films and specially surface-coordinated MOFs (SURMOFs) [13,14] are known to feature unprecedented polymorphs [15,16] that are not accessible in bulk form and can strongly impact the performance of MOF-based devices. [17,18] Thin-film phases can occur when the MOF building blocks interact with surface groups, such as selfassembled monolayers, [19,15] or when the substrate is covered with a precursor layer (i.e., a metal oxide or hydroxide). [20,21] In addition, the physical state of the reagents that interact with the solid surface (i.e., in solution or the vapor phase) can be a determining factor. [22][23][24] Unfortunately, standard crystal structure solution methods are unsuitable for unknown MOF thin-film phases. In contrast to single-crystal or powder X-ray diffraction (XRD) methods, [25] the number of diffraction peaks observed in MOF thin films is The preparation of thin films is often associated with the appearance of unknown polymorphs, as both the substrate and deposition method can heavily influence crystallization processes. Here, chemical vapor deposition is used to obtain thin films of a copper-isonicotinate (Cu-INA) metal-organic framework (MOF). Starting from copper-based precursor layers (copper oxide and hydroxide), a solid-vapor conversion with vaporized isonicotinic acid in either a dry or humidified atmosphere, yields a new Cu-INA MOF polymorph. It is found that the crystalline order of the precursor layer has a strong impact on the texture of Cu-INA thin films. Furthermore, a novel methodology is introduced to determine the structure of a previously unknown thin-film phase of Cu-INA. Although only a few diffraction peaks are found via synchrotron grazing incidence X-ray diffraction (GIXRD), a triclinic unit cell can be determined, and Patterson functions can be calculated. The latter reveals the position of the copper atoms within the unit cell and the alignment of the INA linkers defining the coordination network structure. This work introduces how the combination of GIXRD data with Patterson functions can be used to identify the structure of an unknown thin-film MOF polymorph.

A series of zinc(II) coordination polymers with 5-methoxyisophthalate (CH 3 O-H 2 ip) and five related flexible N-donor ancillary ligands, [Zn(CH 3 , have been synthesized under hydrothermal conditions. Complexes 1-5 were structurally characterized by elemental analysis, infrared spectra and X-ray single-crystal diffraction. These complexes display different types of entanglements. Complex 1 features an extended 3D polythreaded network based on 2D coordination frameworks with a (3,4)-connected (4 2 .6)(4 2 .6 3 .8) topology. Complex 2 shows a rare example of entangled coordination polymer containing both interpenetrating and polythreading features. Complex 3 manifests a highly corrugated 2D (4,4) layer. The layers are penetrated by each other to give rise to 3D polycatenations. While 4 and 5 exhibit three-fold interpenetrated 3D 4-connected (6 5 .8) and (3,4)-connected (4 2 .6)(4 2 .6.10 2 .12) topologies, respectively. These results suggest that both 5-methoxyisophthalate and N-donor ancillary ligands influence on the final resulting structures. Furthermore, luminescent properties and thermogravimetric properties of these complexes were investigated.
