stk.metal_complex.OctahedralDelta

class stk.metal_complex.OctahedralDelta(metals, ligands, reaction_factory=None, num_processes=1, optimizer=<stk._internal.optimizers.null.NullOptimizer object>, scale_multiplier=1.0)[source]

Bases: MetalComplex

Represents a metal complex topology graph.

Metal building blocks with at least six functional groups are required for this topology.

Ligand building blocks with two functional groups are required for this topology graph.

When using a dict for initialization, a BuildingBlock needs to be assigned to each of the following numbers:

metals: (0, )
ligands: (0, 1, 2)

See MetalComplex for more details and examples.

Initialize a MetalComplex.

Parameters:
  • metals (BuildingBlock | dict[BuildingBlock, tuple[int, ...]]) –

    Can be a dict which maps the BuildingBlock instances to the indices of the vertices in _metal_vertex_prototypes it should be placed on.

    Can also be a BuildingBlock instance, which should be placed on all _metal_vertex_prototypes on the topology graph.

  • ligands (BuildingBlock | dict[BuildingBlock, tuple[int, ...]]) –

    Can be a dict which maps the BuildingBlock instances to the indices of the vertices in _ligand_vertex_prototypes it should be placed on.

    Can also be a BuildingBlock instance, which should be placed on all _ligand_vertex_prototypes on the topology graph.

  • reaction_factory (Optional[ReactionFactory]) – The reaction factory to use for creating bonds between building blocks. If None, a DativeReactionFactory is used, which produces only dative bonds in any reactions done by this topology construction.

  • num_processes (int) – The number of parallel processes to create during construct().

  • optimizer (Optimizer) – Used to optimize the structure of the constructed molecule.

  • scale_multiplier (float) – Scales the positions of the vertices.

Methods

clone

Return a clone.

construct

Construct a ConstructedMolecule.

get_building_blocks

Yield the building blocks.

get_num_building_block

Get the number of times building_block is present.

with_building_blocks

Return a clone holding different building blocks.

clone()

Return a clone.

Returns:

The clone.

Return type:

MetalComplex

construct()

Construct a ConstructedMolecule.

Returns:

The data describing the ConstructedMolecule.

Return type:

ConstructionResult

get_building_blocks()

Yield the building blocks.

Building blocks are yielded in an order based on their position in the topology graph. For two equivalent topology graphs, but with different building blocks, equivalently positioned building blocks will be yielded at the same time.

Yields:

A building block of the topology graph.

Return type:

Iterator[BuildingBlock]

get_num_building_block(building_block)

Get the number of times building_block is present.

Parameters:

building_block (BuildingBlock) – The building block whose frequency in the topology graph is desired.

Returns:

The number of times building_block is present in the topology graph.

Return type:

int

with_building_blocks(building_block_map)

Return a clone holding different building blocks.

Parameters:

building_block_map (dict[BuildingBlock, BuildingBlock]) – Maps a building block in the current topology graph to the building block which should replace it in the clone. If a building block should be not replaced in the clone, it can be omitted from the map.

Returns:

The clone.

Return type:

MetalComplex
