Di-mu-chloro-bis(hapto-1,5-cyclooctadiene)dirhodium(I)

Partition coefficient

Link to relevant study record(s)

Reference

Endpoint:

partition coefficient

Type of information:

migrated information: read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

key study

Study period:

Not reported

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: GLP status not known, information from a published handbook, acceptable with restrictions.

Principles of method if other than guideline:

The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to Exploring QSAR, Hydrophobic, Electronic and Steric Constants states that it is an extensive compilation of published data. Each record is evaluated and the preferred value is identified for each substance. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

Key value for chemical safety assessment

Log Kow (Log Pow):

3.16

at the temperature of:

20 °C

Additional information

Partition coefficient is not a relevant endpoint for inorganic substances, but as this substance is organo-metallic the partition coefficient for the organic component of the substance is provided.

Exploring QSAR, Hydrophobic, Electric, and Steric Constants by Hansch (1995) is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

The log kow of cycloocta-1-5-diene, the organic component of di-µ-chloro-bis(hapto-1,5-cyclooctadiene)dirhodium(I), is 3.16.
