Reactions of [WC1(CO)(3)(bipy)(HgCl)], [bipy = 2,2 -bipyridine], with thioureas were performed giving compounds of the type [WCl(CO)(3)(bipy)(HgCl)L], [L = thiourea (tu); N-methylthiourea (mtu); N,N-dimethyithiourea (dmtu)] in which the coordination sphere of the tungsten atom remained unchanged. The coordination of the thioureas to mercury atom was proved to occur in accord to infrared spectra, through the sulphur atom.

The objective of this work was to implant a geodesic pillar in the campus of Botucatu (Rubião Júnior) of the São Paulo State University (UNESP), using active stations of the Brazilian Net of Continuous Monitoring (RBMC) as reference, aiming at inclusion in the Brazilian Geodesic System (BGS). In the planning of the trace, some aspects of the pillar optimization were considered: the field evaluation, the equipment Receiver GPS Topcon Hiper GGD and the net RBMC were used to trace the height, and the Topcon Tools 6.04 version software was use for the data processing, the ambiguity solution, as well as the treatment of injunctions during the column adjustment. The obtained results allowed the implantation of a more accurate pillar then 1ppm compatible to the RBMC net, meeting the specification of IBGE.
