The polymeric linear chain [AuTl(CCl)] reacts with three terpyridine-type ligands substituted with thiophene groups containing N-donor centres in different relative positions (L1, L2 and L3), leading to the Au(I)/Tl(I) complexes [AuTl(CCl)(L1)] (1), [{AuTl(CCl)}(L2)] (2) and [AuTl(CCl)(L3)] (3). X-Ray diffraction studies reveal that L1 acts as a chelate, while L2 and L3 act as bridging ligands, resulting in different coordination indexes for the thallium(I) centre. These structural differences strongly influence their optical properties, and while compounds 2 and 3 emit near the limit of the visible range, complex 1 emits in the infrared region.

The reaction among [AuAg(CF)(OEt)], PbCl and terpyridine leads to the polymeric complex [{Au(CF)}{Pb(terpy)}] (1). Its crystal structure reveals potential voids close to the lead centres large enough to hold different molecules. The availability of these free sites allows complex 1 to act as a VOC sensor.

Introduction And Objectives: The Third Joint European Task Force on cardiovascular prevention recommended the SCORE function for predicting 10-year cardiovascular mortality should be used to guide decision-making on clinical interventions. The objective of the present study was to calibrate the function for use in Spain.

Methods: A model was developed to apply the hazard ratios for cardiovascular mortality at 10 years in SCORE study cohorts to the mean age- and sex-specific risk factors found in the third survey of the MONICA-Catalonia study (1994-96) and to 10-year cardiovascular survival function for the Spanish population based on mortality rates for the year 2002.
