Net topology

pcu_2x2x2_ec2-1_ax2_1

Ingested production record from mofplus. Per-field provenance in field_sources.

JSON · mfpx

32 vertices and 48 edges in the unit cell. 12 of them leave the cell and continue into a neighbouring one; those are drawn in the accent colour and end at a hollow node. Squares are vertices of coordination 5 or more, circles of 4 or fewer. Drag to rotate, or focus the figure and use the arrow keys.

Transitivity pqrs

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
noneNo Systre key: the name pcu_2x2x2_ec2-1_ax2_1 is not one of the 2930 symbols in the RCSR Systre archive of 2019-06-01, and the MOF+ service supplies no canonical key at all, so neither source we read states one for this net. None is computed here.
Checksum
not recorded

Vertices

No coordination sequence is recorded for this net: the source stores none. Every sequence below is absent — which is a different fact from a sequence of length zero, and is why the field is null rather than an empty list.

One row per distinct vertex. The coordination sequence counts how many vertices lie at each topological distance; the vertex symbol names the shortest ring at each angle of the vertex. The two columns do not carry the same warrant: which of them was corroborated, and which was not, is stated above the table.

Position in the collection

RCSR index
none No RCSR index: the name pcu_2x2x2_ec2-1_ax2_1 is not one of the 2930 symbols in the RCSR Systre archive of 2019-06-01, so this net has no position in that ordering and is listed after every net that does.
Complexity rank
1447 The order the ingest processed this net in, simplest first. A different number from the RCSR index above, meaning a different thing.
