Ingested production record from rcsr+mofplus. Per-field provenance in field_sources.
Crystallographic description
- Spacegroup
- not recorded
- Cell lengths
- a = 2.8287 Å, b = 2.8287 Å, c = 1.1545 Å
- Cell angles
- α = 90.00°, β = 90.00°, γ = 120.00°
- Atoms in cell
- 5
- Transitivity pqrs
- not recorded
- Catenated
- no
- No, on the MOF+ name heuristic: that source marks a catenated net by a -c in its name, which the legacy client filters on, and this is that marker read back. A name heuristic, not a computed property of the topology, and not a measurement either source made.
Canonical key
- Systre key
- (rcsr)The canonical Systre key, copied verbatim from the local RCSR Systre archive of 2019-06-01. It is not computed here and cannot be: no Gavrog/Systre toolchain runs on this machine, so nothing on this site derives, extends, repairs or verifies a key. The checksum served beside it is the one the archive itself carries, copied from the same block, so that this copy can be checked against the upstream file; no checksum is computed or verified here.

Vertices
The mapping of coordination sequences onto vertex classes that the source supplied was checked against a walk over the periodic topology of the net itself, one walk per vertex class, and agreed. The sequences are the values the source supplied; the walk settled nothing but which class each one describes.
Not corroborated. The coordination sequences beside these symbols carry a corroboration of their own, stated under coordination_sequences; the vertex symbols carry none. A vertex symbol names the shortest ring at each angle of a vertex, no ring perception runs anywhere in this project, and so there is nothing here that could reproduce one: these strings are served on the word of the source alone. What was checked is their shape — a d-coordinated vertex has d(d-1)/2 angles and a whole symbol names a ring at each, and a string that lists fewer is flagged rather than served as a symbol. A string that passes that count can still be wrong in its rings, and nothing here says otherwise.

Position in the collection
- RCSR index
- 1894 (derived) Derived by this site, not published by RCSR: the 1-based position of the symbol in the ascending ASCII-lexicographic ordering of the 2930 symbols in the RCSR Systre archive of 2019-06-01. RCSR does not number its nets; this is our ordering of their symbols and nothing more.
- Complexity rank
- 135 The order the ingest processed this net in, simplest first. A different number from the RCSR index above, meaning a different thing.
