A total of 4548 frames were collected with a frame width of 1° covering up to 66.21° with 97.7 completeness accomplished. Two single crystal X-ray diffractometers (one Bruker APEX DUO equipped with Mo and Cu sources, and one Bruker X8 APEX equipped with a Mo source) Two powder X-ray diffractometers (Bruker D8 Advance and Bruker D8 Discover equipped with a GADDS detector). Single-crystal intensity data were collected using a Bruker APEX DUO with Mo K radiation (wavelength 0.71073 ) at 100 K. Easy upgradeability protects your investment with maximum flexibility for future extensions. It is engineered with high modularity from best-in-class components and is available in popular all-air-cooled configurations. First-time users should click here for an Introduction to Integration and here for a step-by-step guide to using the Apex-Duo. Remarkably, the BIBP pillar yields bsn (beta-Sn) topology, the BIPY pillar pcu (α-Po) topology. The intensity data was collected on a Bruker Apex DUO 4 K CCD diffractometer using an exposure time of 5 s/frame. The D8 VENTURE offers highest experimental flexibility, with excellent sample accessibility and visibility. Cu-radiation for absolute configuration and protein screening.
In 5– 7 these sql nets are additionally linked by BIBP or BIPY ligands as pillars to provide pillared-layer 3D and three-fold interpenetrated frameworks. Bruker APEX DUO (2011) (Oxford Cryosystems Cobra LT unit) Bruker D8 Quest ECO (Dec 2015) (Oxford Cryosystems LT unit) Bruker D2 Phaser (Dec 2015) Services provided by the facility include data collection, unit cell determination, data reduction, space group determination, molecular structure solution and refinement. Furthermore, the L 2− ligands link the SBUs to a (4,4) 2D sql net. Interestingly, this is a new polymorph of (16), which has been prepared by a different method to the known polymorph (Alléaume et al., 1976) and has been confirmed by powder X-ray diffraction analysis of bulk samples of both polymorphs, as well as a comparative data collection on a Bruker APEX DUO (see § 8). The metal atoms are five coordinated with distorted square pyramidal coordination geometry by oxygen atoms from carboxylate groups of four different L 2− linkers, and one axial DEF-O atom in 3 and 4, BIBP-imidazolyl-N atom in 5 and 6 or BIPY-N atom in 7. Seven compounds, that include the solvate H 2L♲DMSO ( 1♲DMSO), the 1D coordination polymer n ( 2), the two 2D coordination polymers. Independent research in chemistry is encouraged at all levels to provide students with the opportunity to work directly with a faculty member and to gain experience using sophisticated instrumentation, such as a Bruker Avance 300-MHz NMR, Agilent quadrupole time-of-flight (Q-TOF) LC-MS, and a Bruker APEX-DUO dual source (Mo and Cu) CCD X-ray. The APEX-Q platform combines a Q-q- front-end and a high field. The elongated linker 2′,3′,5′,6′-tetramethylterphenyl-4,4″-dicarboxylic acid (H 2L) was employed in the synthesis of zinc(II) and cobalt(II) coordination polymers with single or mixed bridging ligands.
