Materials Data on AgBH8C4(N2F)4 by Materials Project

AgH8(CN2)4BF4 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two BF4 clusters and one AgH8(CN2)4 ribbon oriented in the (1, 0, 0) direction. In each BF4 cluster, B3+ is bonded in a tetrahedral geometry to four F1- atoms. There are a spread of B–F bond distances ranging from 1.41–1.43 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one B3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one B3+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one B3+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one B3+ atom. In the AgH8(CN2)4 ribbon, Ag1+ is bonded in a 2-coordinate geometry to four N3- atoms. There are a spread of Ag–N bond distances ranging from 2.13–2.88 Å. There are four inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.18 Å) and one longer (1.30 Å) C–N bond length. In the second C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.18 Å) and one longer (1.30 Å) C–N bond length. In the third C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There is two shorter (1.34 Å) and one longer (1.36 Å) C–N bond length. In the fourth C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There are a spread of C–N bond distances ranging from 1.33–1.35 Å. There are eight inequivalent N3- sites. In the first N3- site, N3- is bonded in a linear geometry to one Ag1+ and one C4+ atom. In the second N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. There is one shorter (1.01 Å) and one longer (1.02 Å) N–H bond length. In the third N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the fourth N3- site, N3- is bonded in a bent 120 degrees geometry to one Ag1+ and two C4+ atoms. In the fifth N3- site, N3- is bonded in a distorted linear geometry to one Ag1+ and one C4+ atom. In the sixth N3- site, N3- is bonded in a distorted bent 120 degrees geometry to one Ag1+ and two C4+ atoms. In the seventh N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.01 Å. In the eighth N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom.

Visualization of Upcoming ISS Changes - Featuring MLM Install

The MAGIK Robotic analysis team provides kinematic feasibility assessments and robotic visualizations for the ISS. The latest visualization displays ISS planned operations in increments 65 and 66 as of the 7/6/21 flight plan. Featured events include the arrival of the Multipurpose Laboratory Module (MLM) and surrounding visiting vehicle actions. The complete list of actions shown include: Repeated ISS attitude adjustment maneuvers from: starting position with positive X Velocity Vector (+XVV), yaw to -XVV, and pitch to final position with -ZVV. Then subsequent return to -XVV and nominal position +XVV. Crew-2 relocation from Node 2 Forward (N2F) to Node 2 Zenith (N2Z). 77 Progress with Docking Compartment 1 (DC1) undock and departure. MLM install. Boe-OFT2 arrival and departure at N2F. NG-16 arrival and berth at Node 1 Nadir (N1N). SpX-23 arrival at N2F. 64 Soyuz relocation and fly-around. SpX-23 departure from N2F. 65 Soyuz approach and dock to MRM-1. 64 Soyuz undock and departure. 78 Progress relocation.
