(5Z)-5-(2-Hydroxy­benzyl­idene)-3-phenyl-2-thioxo-1,3-thia­zolidin-4-one

In the title compound, C16H11NO2S2, the dihedral angles between the heterocyclic ring and the phenyl and anilinic benzene rings are 9.68 (13) and 79.26 (6)°, respectively, and an intra­molecular C—H⋯S inter­action occurs. In the crystal, inversion dimers linked by pairs of O—H⋯O hydrogen bonds occur, leading to R 2 2(10) loops, and C—H⋯O and weak C—H⋯π inter­actions further consolidate the packing

(5Z)-5-(2-Methyl­benzyl­idene)-3-phenyl-2-thioxo-1,3-thia­zolidin-4-one

In the title compound, C17H13NOS2, the heterocyclic ring is oriented at a dihedral angle of 74.43 (5)° with respect to the anilinic benzene ring and at a dihedral angle of 17.31 (9)° with respect to phenyl ring. An intra­molecular C—H⋯S inter­action occurs, resulting in an S(6) ring. In the crystal, the packing is consolidated by C—H⋯π inter­actions and possible very weak aromatic π–π stacking [centroid–centroid separation = 4.025 (1) Å]

HadISD: a quality-controlled global synoptic report database for selected variables at long-term stations from 1973--2011

[Abridged] This paper describes the creation of HadISD: an automatically quality-controlled synoptic resolution dataset of temperature, dewpoint temperature, sea-level pressure, wind speed, wind direction and cloud cover from global weather stations for 1973--2011. The full dataset consists of over 6000 stations, with 3427 long-term stations deemed to have sufficient sampling and quality for climate applications requiring sub-daily resolution. As with other surface datasets, coverage is heavily skewed towards Northern Hemisphere mid-latitudes. The dataset is constructed from a large pre-existing ASCII flatfile data bank that represents over a decade of substantial effort at data retrieval, reformatting and provision. These raw data have had varying levels of quality control applied to them by individual data providers. The work proceeded in several steps: merging stations with multiple reporting identifiers; reformatting to netCDF; quality control; and then filtering to form a final dataset. Particular attention has been paid to maintaining true extreme values where possible within an automated, objective process. Detailed validation has been performed on a subset of global stations and also on UK data using known extreme events to help finalise the QC tests. Further validation was performed on a selection of extreme events world-wide (Hurricane Katrina in 2005, the cold snap in Alaska in 1989 and heat waves in SE Australia in 2009). Although the filtering has removed the poorest station records, no attempt has been made to homogenise the data thus far. Hence non-climatic, time-varying errors may still exist in many of the individual station records and care is needed in inferring long-term trends from these data. A version-control system has been constructed for this dataset to allow for the clear documentation of any updates and corrections in the future.Comment: Published in Climate of the Past, www.clim-past.net/8/1649/2012/. 31 pages, 23 figures, 9 pages.

3-(3-Methyl­phen­yl)-2-thioxo-1,3-thia­zolidin-4-one

In the title compound, C10H9NOS2, the dihedral angle between the rhodanine (2-thioxo-1,3-thia­zolidin-4-one) and 3-methyl­phenyl rings is 83.30 (3)°. The H atoms of the methyl group are disordered over two set of sites with an occupancy ratio of 0.58 (3):0.42 (3). In the crystal, the mol­ecules inter­act by way of C—H⋯π and C=O⋯π inter­actions

(5E)-5-(4-Hydr­oxy-3-methoxy­benzyl­idene)-2-thioxo-1,3-thia­zolidin-4-one methanol monosolvate

In the title compound, C11H9NO3S2·CH4O, the dihedral angle between the aromatic rings is 3.57 (16)° and intra­molecular O—H⋯O and C—H⋯S inter­actions occur. In the crystal, the thia­zolidin-4-one mol­ecules are linked by N—H⋯O hydrogen bonds, forming chains. The hydrogen-bond motifs lead to S(5), S(6) and R 3 3(8) ring motifs. There exist C=O⋯π inter­actions between the heterocyclic rings and π–π inter­actions between the heterocyclic and benzene rings at distances of 3.455 (2) and 3.602 (2) Å, respectively. The methanol solvent mol­ecule is disordered over two sets of sites in a 0.542 (9):0.458 (9) ratio

In the title compound, C10H7NO2S2·0.5CH3OH, the dihedral angle between the aromatic rings is 11.43 (11)° and a short intra­molecular C—H⋯S contact occurs. The methanol solvent mol­ecule is equally disordered over two sets of sites. In the crystal, inversion dimers linked by pairs of N—H⋯O hydrogen bonds occur. The methanol solvent mol­ecule connects the dimers through O—H⋯S and O—H⋯O inter­molecular hydrogen bonds. Further stability is afforded by C—H⋯π and π–π inter­actions [centroid–centroid separation = 3.5948 (13) Å]

In the title compound, C9H9ClN2OS, the 3-chloro­phenyl and acetyl­thio­urea fragments are oriented at a dihedral angle of 62.68 (5)°. An intra­molecular N—H⋯O hydrogen bond generates an S(6) ring motif. Mol­ecules are linked into dimers via a cyclic R 2 2(8) motif of N—H⋯S hydrogen bonds. These dimers are further connected through C—H⋯S inter­actions, completing an R 2 2(12) motif, into chains along [010]
